Speaking of wierd crashes, we have a MacII that caused us headaches
for a long time.  I never noticed a correlation with the color setting.
But it would crash, intermittently at first, and at seemingly random
points: while in an application, while on the desktop, when accessing
the hard disk, when just moving the mouse around, or when opening a file.
We had the motherboard changed, memory chips changed, various diagnostics
programs run with no findings, and we had it sit in the shop for a month or
two, all with no effect.  Then we noticed that, when the problem arose,
if we opened up the computer, took out the video board, generally fiddled
with it (maybe randomly press chips down, or other superstitious behavior),
and replaced it, the problem would go away for a few days.

So, as we have a second MacII, we used the scientific method, played
swaptronics, and convinced ourselves that the video board was at fault.
This was even though diagnostics programs showed it to be just fine.  The
video card was replaced a few days ago, and looks like no more problems.

But it certainly was a wierd-looking problem while it lasted.
