Approach this methodically!
1) As I recall, there were some funny things that went on having to do
with the Appearance Manager. There's a patch (the URL escapes me...).
2) Check your extensions. Since things worked just fine for a while
(presumably under MacOS 8.1), you've either added an extension or
changed a setting on an extension which is then interfering with
Mathematica. If you use Conflict Catcher, you can sort the extensions
list by date installed to narrow down the culprits.
3) Have you run Norton or Disk First Aid?
4) Have you tried moving your Mathematica preferences, so Mathematica
has to resort to using
defaults? Wierd problems sometimes track to a bad preferences file.
5) Check your fonts. Every once in a while, a font file will develop a
glitch and you'll either crash when using the font, or get cosmetic
problems. If this is the problem, simply replace the font file.
BTW, items 2-4 apply to almost any problem on the Mac and probably
of all problems. Notice too that I haven't even mentioned viruses.
Even with the recent "explosion" of viruses, the fact remains that the
Mac is roughly *two orders of magnitude* behind PCs on virus count.
Most Mac viruses are MS Office macro viruses that afflict both Windows
& MacOS. I'd classify nearly all the remaining known Mac viruses as
extinct. I've been using the Mac for more than 13 years and have
never been infected. In all this time I've received only two or three
infected files which were promptly
caught by virus checking software. I'm getting long-winded here because
folks on the Mac often see a glitch and think 'virus' when that should
be *way* down on the list of suspects. [My guess is that anti-virus
competent enough that even on Windows, 'virus' is probably not the first
to worry about...]
