My Mac has decided that every time I touch any menu item in Excel 2.2
the program will shut down with a message (from Multifinder?)

   "The application "Microsoft Excel" has unexpectedly quit (3)"

sometimes followed by the system freezing.

The whole system (an SE/30, 8 MB, 3 HDs,System 6.0.5) has worked fine
'til now , and nothing new in INITs or the like was loaded recently.
Have reinstalled complete system from locked 6.0.5 System Tools disks;
reinstalled complete Excel from locked master disks; given Excel
double the memory it asks for; given it GateKeeper privileges; done
all this several times -- still does this.

WriteNow, QUED/M, MicroPhone, Microsoft WORD, all work fine.  Excel
itself opens fine, will obey keyboard equivalents of menu commands
(Open, Save, Quit, etc.), and accept entries in cells.  The Apple menu
works, the Multifinder icons will shift among applications.  But click
on any Excel menu head and it quits.  (If you start up with just the
Finder, you get a system crash, ID=10).
