What are the problematic corruptible "Naughty Nine" Preference Files of the Classic Mac OS ?
(Specifically, 7.5.5 through 9.2.2 in this case scenario for crashes, bombs & unexpected quits)
In the Preference Folder in the System Folder:
Apple Menu Options
Date and Time
Move them to the trash but do not delete; restart first, then when reboot finishes, delete.
A "tenth" preference would be "Finder" Preferences,
which is also a well-known preference file susceptible to corruption.
One could trash this one also.
