Like the other System 7 bug reports, I tried this one.  Unlike the other
System 7 bug reports, this one actually crashed my system.

DO NOT TRY TO REPRODUCE THIS CRASH UNLESS YOU ARE WILLING TO REFORMAT
YOUR SYSTEM DISK AFTERWARDS!

After the choosing the color extension, I hit the popup items and looked at
the menus.  Fine.  When I hit the close box, the drive started to whir and
the light went on.  Like Matt I waited a while, and then gave up and hit
the Reset switch.  When the system tried to reboot, I saw the happy mac,
and then got a Sad Mac error code when the screen went black.  I believe
the error code was all 0s and an F on the first line and 0s then 2?
on the second line (the ? is a place holder - I'm not sure of the actual
character).

My system is identical to Matt's except that I have an Apple installed
Quantum 40M internal.  Also (and what saved me) I have an external 85M.
After rebooting from an old locked floppy, the drive mounted normally.
Disk First Aid stated that there was a problem it could not fix on the
Internal drive.  Fine.  So I copied all of the stuff except for the now
corrupted System file to the other drive and reformatted the internal.

Here's where it gets odd:

After reinstalling from orignal 7 disks (I got the HD images just last night),
I tried to reproduce the crash.  NOTHING HAPPENED!  So, what caused the
problem I do not know.

If anyone is interested (particularly someone from Apple's testing dept.)
in following up on this, I can provide a list of concurrently running programs
and installed extensions.
