INTRODUCTION
This is a FAQ (Frequently Asked Questions) list to cover common questions
relating to use of Berkeley System's After Dark screensaver package on the
Macintosh platform.

This FAQ does not cover the use of After Dark on the Windows platform. (I
don't use a Windows unless I really have to, Windows supports its own
screensavers without requiring an additional package like After Dark, and
this was originally posted to a Macintosh newsgroup. Go figure :-)

The information in this FAQ is based on my experience with After Dark and
tidbits I have gleaned from email from writers of third-party After Dark
modules and with Berkeley Systems. I have no connection with Berkeley
Systems other than as a satisfied user of After Dark and More After Dark.

I welcome comments and corrections, although email turnaround will be slow
due to pressure of work and the relatively low priority something as
frivolous as this gets. At the moment, the FAQ is not particularly
comprehensive or organised, and information is often repeated - style will
(I hope) come with time. Comments on how to write and archive FAQs are also
welcome.

This FAQ does not cover Star Trek: The Screensaver, or the two After Dark
book/disk collections - I don't own them - or hints on using certain
modules, because I can't think of any useful ones. Anyone want to
contribute any module-specific tips?

The FAQ is aimed at detailing common problems and misconceptions,
concentrating on 'why does After Dark crash my machine?' The answer is
almost always a badly-written third-party module running under the
MultiModule or Randomiser modules. These modules impose stricter rules on
how a module can run than After Dark alone does, and a large number of
third party (shareware/freeware) modules either won't run as a sub-module,
crash the Macintosh, or have other, unpredictable, effects.



DO I NEED A SCREENSAVER? (0.0)
Despite what many people will tell you, the answer is almost certainly
'no'. It takes a lot of time to burn the phosphor on a cathode ray tube
with a still image - accidentally leaving your Mac on all weekend won't do
it, so don't worry if you do. Old Mac Plusses or monochrome Mac monitors
that have seen years of service may have a ghostly bar at the top of the
screen from the menu bar, visible when a menu bar is not present, but
that's about it. The phosphor on colour monitors is even more difficult to
burn, making screensavers even less useful.

If you own a Mac with an LCD display (a PowerBook, Portable or Outbound)
you are unlikely to need a screensaver. LCDs retain the colour they are set
to in a 'memory effect' which takes time to change, whether black or white,
but does fade away. If you use a (probably unnecessary) screensaver, it has
been suggested that it should be one which flips all of the pixels
regularly, to prevent this memory effect. [Note - this is unrelated to the
ni-cad battery 'memory effect' fallacy. More information on both of these
topics can be found in the PowerBook FAQs of the Mac newsgroups.]

If you have just bought a Color Classic, you should be using the Screen
control panel supplied with the System Software to turn off the monitor
circuitry when the Color Classic is not in use - you DO NOT need a
screensaver. 

Screensavers are primarily fun, decorative things to have around, and
should not be taken seriously. A screensaver is useful for protecting your
Mac from prying eyes while you are away from it, and many screensavers
include optional password features.



What are the alternatives to After Dark? (0.1)
After Dark is by no means the only Mac screensaver - it's just the most
popular and has the most support from other programmers in the form of
different screensaver 'modules'. It's commercial and costs money, although
updates and bug fixes are free.

As After Dark is commercial, it CANNOT be obtained from ftp sites. Updaters
can be obtained by ftp, but they must update the original package which you
have bought. If you want to use After Dark modules, you must buy After Dark
(or wait for the next release of DarkSide, which is freeware and WILL run
After Dark modules. See below.)

If you are looking for a screensaver, it is well worth obtaining shareware
and freeware savers from ftp sites and evaluating them before looking at
the more expensive commercial products.

Alternatives to After Dark that are modular, with a number of different
effects, include:

Pyro! (currently v4.0 and revisions) - commercial. This is the original
'fireworks' screensaver. One or two third-party modules do exist, but
nowhere near the volume After Dark has. [Like After Dark, Pyro! has a fish
module. Although it's generally regarded as not as cute, the fish in Pyro!
can eat each other.]

DarkSide of the Mac (currently v3.2) - freeware, by Tom Dowdy, an Apple
employee. Some third-party modules exist, and there is a password feature
and randomiser. DarkSide runs as a startup application under System 7,
which is both its greatest strength (stability and no patch trapping) and
weakness (System 6 users require the older DarkSide of the Mac v2.5, the
last version to run under System 6).
Many modules (Searchlight, Worms) are similar to After Dark's and Pyro's,
but with less cute frills. Others (Circuit, LostInSpace, VaseDance) are
original and well worth a look. A copy can be ftp'ed from
sumex-aim.stanford.edu (it's in the util directory). Version 4.0 is
currently in beta-test, and adds the ability to play After Dark modules.

There are a large number of standalone screensavers to choose from, and
many are present in the util directory of sumex-aim. Moire (also available
as an After Dark module) and Eclipse are popular choices. There are a
number of specialised screensavers for Macs that support use of the
Brightness control panel.



HOW CAN I UPDATE MY COPY OF AFTER DARK? (1.0)
Well, what version of After Dark do you own? There are two major revisions,
namely versions 1 and 2. When someone mentions they own 'After Dark', you
can assume if it is not otherwise stated that they mean version 2, of which
there have been a number of minor revisions in the past few years, detailed
below. Version 2.0 was released back in August 1990, so version 1 is OLD.
No self-respecting Mac poser in this day and age would be seen dead running
Version 1. So there.


HOW CAN I UPDATE MY COPY OF AFTER DARK v1.x? (1.1)
An updater to 1.1c is available from sites on the Internet. If you are
already running 1.1c and wish to upgrade to version 2, you can do so by
returning your disk to Berkeley Systems with $15. There is NO free updater
from version 1 to version 2.

You may find that version 1.1c fails to work on the brand-spanking new Mac*
you have just bought. If so, trash it or upgrade to version 2. (see 1.2)

*Here, even a clapped-out IIci can qualify as 'brand-spanking new'. Version
1 is THAT OLD.


HOW CAN I UPDATE MY COPY OF AFTER DARK v2.x? (1.2)
An updater to update the various revisions of version 2 to the latest
revision can always be found in the info-mac archive on
sumex-aim.stanford.edu (directory: util/ad) or on one of the mirror sites
scattered world-wide. Berkeley Systems issues updaters periodically, in
line with new Apple machines or System software. The updater generally
takes up to a couple of weeks from release to reach sumex-aim, so patience
is called for if you have heard rumours of an updater but can't find it
yet.

The updater updates version 2 revisions - NOT version 1 - to the latest
revision, currently 2.0x updater 1.02. This updates both the control panel
and all of the modules supplied with the After Dark package, making minor
revisions throughout. [The previous updater, 2.0w, was unusual in only
updating the control panel, MultiModule and Randomiser. If you have 2.0w,
get the 2.0x updater.]

There is generally no reason not to upgrade. As a rule of thumb, the newer
your model of Mac and/or System, the newer your copy of After Dark needs to
be, and if you have access to anonymous ftp or something friendlier like
Fetch, grabbing the updater is not very difficult (ask a friendly guru :-).
This FAQ assumes that you have the latest revision of version 2 (2.0x at
time of writing).

Alternatively, you can return your master disk to Berkeley Systems to have
it updated, or buy More After Dark, which includes an updater (2.0u or
later, depending on when the MAD disk was mastered.)

The version history of the updater releases (not detailing the numerous
minor improvements or feature additions to modules) is:
2.0 - August 1990 - initial release.
2.0h - Bug fix relating to using HyperCard with After Dark.
2.0s - Bug fix of sound code.
2.0t - September 1991 - Supports new sound code of System 6.0.7.
2.0u - June 1991 - Full System 7 compatibility. Understands the new System
Folder layout and is much faster when only the Finder is running.
2.0v - August 1991 - Fixed 68040 cache-compatibility problems.
2.0w - September 1992 - Fixed problems with the new machines running System
7.1 (IIvx, Duos) - old machines running System 7.1 could still use 2.0v.
Added 'All' and 'None' buttons to the Randomiser. Detects when Randomiser
and MultiModule recursively launch each other and prevents it. [2.0w is
unusual in only updating the control panel, MultiModule and Randomiser, and
not other modules. Star Trek: The Screensaver 2.0w has more in common with
After Dark 2.0x in terms of features than it does with After Dark 2.0w]
2.0x - February 1993 - new control panel icon, clears password, more 'When'
options, muting sound via the control key. Slide Show now works with
QuickTime. Brings After Dark and Star Trek into line with each other.

(Updater release information from Jim Tso at Berkeley Systems)


HOW CAN I UPDATE MY COPY OF STAR TREK: THE SCREENSAVER? (1.3)
At time of writing, by applying a revision 2 updater LATER THAN 2.0w (the
first version of Star Trek: the Screensaver) i.e. 2.0x or later. This will
update the control panel and modules shared in common with the After Dark
package (Randomiser, MultiModule).

At time of writing, there is no updater for the Star Trek modules. A
ResEdit template for extracting PICT resources from the Star Trek files is
available from a number of ftp sites, for use by the inquisitive.


HOW CAN I UPDATE MY COPY OF MORE AFTER DARK? (1.4)
At time of writing, there isn't an updater for these modules, although one
is reportedly under development. There was a minor revision of MAD from 1.0
to 1.0a to fix some apparently obscure bugs - this is only available by
returning your disk to Berkeley Systems, and there is no equivalent
updater. I haven't seen this revision, and don't know what it fixes.
Personally, I would wait for the new updater to hit the nets.


HOW CAN I UPDATE MY MODULES OR OBTAIN NEW MODULES? (1.5)
If the modules are part of the After Dark package which you have bought,
you need the updater that also updates the control panel (see 1.2). If they
are part of the MAD package which you have bought, sit and wait (see 1.4).
If they are shareware or freeware, look at sumex-aim.stanford.edu (util/ad
directory) to see if a later version has been released. This is also the
place to look for new modules - read the info-mac digest
(comp.sys.mac.digest) for news of new Mac software, including After Dark
modules.

If you are having problems with a particular third-party module, see first
if a later version is available from an ftp site like sumex-aim. If not,
contact the author of the module about the problem. This is easily done if
an email address is given, and the authors do appreciate feedback, if not
cold hard cash. :-)



HELP! I'VE FORGOTTEN MY SCREENSAVER PASSWORD, AND CAN'T USE MY MAC! (2.0)
A common problem. If you are using System 7, hold down the shift key on
reboot (reset button or command-control-power on newer Macs) to disable all
extensions and control panels, including After Dark.

If you are running System 6, you will need to startup from a floppy disk
instead of holding down the shift key, unless you have installed an
'extensions manager' and can use that instead.

Then replace the control panel with a fresh copy from your master disk.
Restart and enter a new password.

If you have stupidly misplaced your master disk, try grabbing a copy of the
2.0x (or later) updater and update the control panel instead of replacing
it. 2.0x is the first updater to clear the password on updating the control
panel.



WHERE SHOULD I PUT THE 'AFTER DARK FILES' FOLDER? (3.0)
If After Dark can't find the modules that are sitting as they should be in
the 'After Dark files' folder, you probably need to update After Dark.
Versions 2.0u and later of After Dark will recognise the folder in System
7's Control Panels folder, in the Extensions and System folder, and on the
Desktop, whereas 2.0t and before expected the After Dark control panel and
files folder to be in the same place.

If you are using AutoDoubler 1.0x, you could try putting the After Dark
files folder on the Desktop so that AutoDoubler can compress it. This works
well as long as MultiModule and Randomiser are not deliberately compressed.

[AutoDoubler users should see the comments on the PowerDown module in
Section 5.2 as well].



MY AFTER DARK CONTROL PANEL AND MODULES HAVE LOST THEIR ICONS! (4.0)
There are a couple of module floating around that have accidentally had
their 'bundle bits' set, and you have just obtained one of these modules or
just rebuilt your desktop, bringing the problem to light.

The 'bundle bit' of a file tells the Finder that the file has icon
information the Finder must show. A module with a bundle bit set causes its
(non-existent) icon information to replace After Dark's correct icon
information.

To fix this, you need a utility that will show file flags, such as ResEdit
or FileTyper. Go through all your modules, bringing up the file flag
information (This is the 'Has BNDL' box under 'Get File/Folder menu in
ResEdit 2.1.1's File menu) and make sure the bundle bit is cleared. If it
isn't, clear it and save that file.

Once you have done that, restart and hold down <option> and <command> to
rebuild your desktop. You will then see the After Dark icons in all their
glory. [Just don't ask me why there aren't any ics resources for the
modules or MultiModule documents. I don't know!]



AFTER DARK CRASHES MY MACHINE! (5.0)
Er... probably not. It's far more likely to be an individual module than
After Dark itself, so let's do some fault analysis to see why.

Firstly, have you updated your copy of After Dark to the latest version
with the free updater detailed earlier? If not, try updating a copy, and
see if the problem goes away. This is likely to solve the 'After Dark
doesn't work at all on my machine!' problem.

If you are already running the latest version, have you bought a
just-released Mac or just-released System? If so, an update may be in the
works - just ask Berkeley Systems. If not, is the problem with a specific
module, and can you isolate it by trying out different modules?

If the problem is with a module written by Berkeley Systems, well and good,
provided that the module is NOT the RANDOMISER or MULTIMODULE. You can
happily adopt a suitable tone of moral outrage and grumble at them on the
email address given with their packaging (they have a number of scattered
accounts - replying to the one that replied to your query is a sensible
idea). 

If the module is from a third-party (shareware/freeware) and you cannot
find a later version anywhere, you should be grumbling to the author of the
module (again via email).

If you are having trouble with the MULTIMODULE OR RANDOMISER, this is where
the fun starts, as a large number of third-party modules don't work well
with these, often causing crashes, and giving After Dark a reputation for
crashing in the process. If you are not running any third-party modules
under the MultiModule or Randomiser, you can grumble at Berkeley Systems.
If you ARE, consult the list below to see if the problem has been
encountered, and see if grumbling at the author of the module helps. Look
around the net for a later (bug-fixed) version of the module.

When trying out a new After Dark module, try it as the only module selected
in the Randomiser, and see how well it behaves. If you use the Randomiser a
lot, this is an easy way of spotting problem modules before they crash your
machine and lose you work.


MODULES THAT DON'T WORK UNDER MULTIMODULE AND RANDOMISER (5.1)
This list has been compiled from information mostly obtained by running
After Dark along with lots of other extensions on a Mac IIsi and LC that
have variously run Systems 7.0 and 7.0.1 (alone and with Tune-Up 1.0 and
1.1.1, although that doesn't matter) and System 7.1. After Dark versions
2.0t, v, w and x were used.

This list details modules that 'work fine' EXCEPT when run under
MultiModule or Randomiser (or both - the author of this FAQ currently runs
Randomiser, randomising a lot of modules every five minutes, in parallel
with Dan Walkowski's PowerDown, which shuts off an unused Mac, under
MultiModule. This catches more problem modules than most - your mileage may
vary, and you may not encounter some of these problems on your set-up,
particularly if you are using a Classic or Plus.)

Modules whose latest versions works fine, but whose earlier versions
didn't, are not listed here, as that would entail a version history report
of every After Dark module in existence! If the module you are having a
problem with is not mentioned here, then see if a later version is
available. If not, contact the author of the module about the problem.

If email addresses of the authors are available, they are given. If you are
having problems with a specific module on this list, please contact the
author regarding a bug-fix, NOT me! If you have encountered problems with a
freeware/shareware module NOT on this list, please let me know by email
(and include a binhexed copy of the module so I can try it out) and I'll
update this list. Ditto for updates to the modules here - I'm not
omniscient, and may have missed a bug-fix or two.


MULTIMODULE WITH RANDOMISER
If you use these modules a lot, make sure you have the latest revision of
After Dark. Versions earlier than 2.0w would hang if MultiModule included
Randomiser and Randomiser included MultiModule in its selection, whenever
the Randomiser tried to run the MultiModule which was already running. (Say
'recursion', people.) 2.0w and later detect this and add incredibly useful
'All' and 'None' buttons to the Randomiser [but still no support for my
extended keyboard's extra cursor-control keys, unlike the control panel
itself...]

And now, the third-party list, in alphabetical order:

Balloons - BugByte, Inc, 1991 (no email address)
A very large (340K) module that advertises a HyperCard stack on tying
balloons into knots to make figures and demonstrates some shapes with
accompanying sound effects. Does not run under Randomiser, and puts up a
message saying that not enough memory is available. Does not appear to
crash the Mac.

Bat Signal - subversive software (subversive@aol.com)
A Spotlight-like module, but using the Bat Signal, and with the coolest
about box yet. There are at least two versions of this module in existence,
and both the ones I've seen have no version numbers. The one with the later
modification date works correctly under Randomiser and no longer crashes.
The author says he doesn't have the time to finish the module off properly,
though. Well worth seeing.

Chomp! - Berkeley Systems (brklysystm@aol.com or D0346@applelink.apple.com)
This was one of the original modules for the original After Dark. Bites are
taken out of the screen with a chomping sound. Causes the System 7 Finder
to quit when run under Randomiser with After Dark v2. No longer supported
by Berkeley Systems (although other modules from the same era, like
TacTiles and Shapes, still work fine).

Frect 1.0 - Adam Miller (Adam_Miller@Memory.Ithaca.NY.US, but moved since)
Produces 'fractal rectangles'. Causes the System 7 Finder to quit when run
under Randomiser.
 
HolisticSofa 0.94 - Alan Keahey (tkeahey@cs.indiana.edu or GEnie: A.Keahey)
This module explores the sofa-on-stairs problem detailed in Douglas Adam's
'Dirk Gently's Holistic Detective Agency', but crashes under the Randomiser
on newer Macs. The author wrote it on a Plus, which it didn't crash on, and
can't duplicate the problem. There is also a standalone screensaver version
available.

Kablooie 1.0 - Adam Miller and Jakub Buchowski
(Adam_Miller@Memory.Ithaca.NY.US and Jakub_Buchowski@Memory.Ithaca.NY.US -
the authors have since moved)
A customisable fireworks module for After Dark. Puts up 'Kablooie:' running
under the Randomiser and nothing else. Adam Miller knows of the problem,
but no fix has appeared yet.

Kings Cross Coke 1.0 - John Rotenstein (PO Box 165, Double Bay NSW 2028,
AUSTRALIA)
Shows logos and illuminates them as if they were neon signs. Includes a
scrapbook feature to choose images from. Has memory problems - crashes
under Randomiser and MultiModule, and is pretty flaky on its own,
especially when cutting and pasting in the scrapbook. Spectacular, but
risky.

Millions of Colors v0.5 - Guy T. Rice (CompuServe: 76226,760 GEnie:
GUYRICE)
Bands of colour. Doesn't work under MultiModule. Email to the author
bounced. Package includes source code - anyone want to fix it?

Nebulae 1.0 - Bryan & Lisa Gibson-Winge (Compuserve: 72677,3222)
Complains of not enough memory to run under MultiModule or Randomiser.
Doesn't appear to crash.

Off The Air 1.0 - Guy T. Rice (CompuServe: 76226,760 GEnie: GUYRICE)
Simulates a noisy television channel after the station has gone off air.
Under Randomiser changing modules every few minutes, forces a crash a few
modules after it has run. (Trashing memory?) The 'Set Monitor Depth'
feature is bad ju-ju and can also crash the mac. Email to the author
bounced.

Shredded Crystals - Berkeley Systems (brklysystm@aol.com or
D0346@applelink.apple.com)
This was one of the original modules for the original After Dark. Jagged
shapes appear on screen. Causes the System 7 Finder to quit when run under
Randomiser with After Dark v2. No longer supported by Berkeley Systems
(although other modules from the same era, like TacTiles and Shapes, still
work fine).

Sparkler 1.0 - Mike Wessler(wessler@husc10.harvard.edu until Summer 1992)
Pixels explode off the screen. Crashes under Randomiser. Email to the
author bounced.[Not to be confused with Sparklers 1.0, by Frank Kubin,
which works fine under the MultiModule and Randomiser]

 
MODULES WITH OTHER KNOWN PROBLEMS (5.2)
In alphabetical order:

Movies 'til Dawn 1.0 - Berkeley Systems (brklysystm@aol.com or
D0346@applelink.apple.com)
This free QuickTime movie player module worked fine with QuickTime 1.0/1.1,
but doesn't work at all with QuickTime 1.5. Trash it - a new version is due
Real Soon Now (just after that MAD updater mentioned in 1.4). Playing
movies is a pretty pointless activity for a screensaver, since it may save
your screen, but kills your hard disk through overwork. (Not recommended
for portables, where the hard disk spins down to save battery power.) If
you MUST play movies in the meantime, look at Movies in the Dark 1.0 by
Maurice Volaski or the OURA QT (say each letter!) QuickTime movie player
1.0d2 by Laurence d'Oliveiro.
Note that Slide Show 2.1 (with 2.0x or later) can display QuickTime
JPEG-compressed PICT files, which is far more useful for a screensaver than
playing movies. (Slide Show 2.0 or earlier will always hang on the second
screensave if a QuickTime JPEG is used.) If you DO use JPEG pictures with
Slide Show 2.1, remember that pictures are uncompressed with a blank
screen. If the screen is blank, After Dark will not wake until QuickTime
has finished decompressing the picture. If you have the password feature
enabled, you may have to type the password blind.

Paw-Paw 1.2b - Aaron Barnet (c2mxbar@fre.fsu.umd.edu)
Known problems when running over Microsoft Excel or Word. Tested and found
that it ran correctly in Demo mode, but trashed After Dark, requiring
reinstallation, when selected as a screensaver. The author is working on
these problems.

PowerDown 1.1 - Dan Walkowski (walkowsk@cs.uiuc.edu)
Shuts off an unattended Mac after a pre-set time.
Running PowerDown in parallel with Randomiser under MultiModule with the
After Dark files folder on the Desktop so that AutoDoubler 1.0.7i could
compress it (whew!) led to extra copies of the modules running when
PowerDown shut downs being put in an AutoDoubler folder. Telling
AutoDoubler not to compress PowerDown, Randomiser and MultiModule prevented
this from happening - somewhere, somehow, a file wasn't being closed
properly.
[If you are using PowerDown, take a look at the Okey-Dokey 1.01 control
panel from the same author, which will press the default button in a dialog
after a pre-set time. This allows you to have open documents in most
applications saved automatically on shutdown]

Virex-D (MAD 1.0) - Berkeley Systems (brklysystm@aol.com or
D0346@applelink.apple.com)
Virex-D is primarily an advertisement for the commercial Virex
virus-killer. As the D indicates, Virex-D DETECTS viruses - it does not
remove them or repair damage. Virex-D has not been updated recently (and
will not be until the MAD updater mentioned in 1.4 appears), and SHOULD NOT
be used for virus protection. As a screensaver, it kills your disk
unnecessarily, too.
Use the freeware Disinfectant application (version 3.0 at time of writing)
and/or Gatekeeper system extension (version 1.2.7 at time of writing),
available from all good ftp sites, to combat Mac viruses. Remember that
most Mac viruses are relatively benign and are very rarely seen - this is
not something to lose sleep over. [Read the excellent Disinfectant on-line
help for more information.]

VoiceWaker 1.03 - Alessandro Levi Montalcini (Fricci@Polito.IT)
This module works with a microphone to wake up a Mac when you shout at it
(A neat trick - just say 'Wake up!' and pretend you're running Caspar...
:-) If you are using a Global Village Teleport ADB modem, the Mac will hang
whenever a screensave starts. The author can't see a problem with his code,
and does not have an ADB modem to play with, so a fix is unlikely.

world, and this FAQ tries to reflect the state of a moving target as best
it can.
