I (accidentally) stumbled on something which appears to be an easily
repeatable method of crashing my machine...The specifics are as follows:

System:  Mac IIcx, 8/80, extensions disabled at startup (shift key).
         Running System 7.0 Golden Master.  Miscellaneous hardware
         attached is limited to an Apple Data Modem 2400.  Virtual
         memory is off.

Situation:  I created an alias to the trash can.  I dragged this alias
onto the main (root level) window of my hard disk.  At this point, I
renamed 'Trash Alias' to 'Trashcan'  (The view on my main window is
set to 'by Icon', and my disk contains about 60MB of data, if it makes
any difference...). 

Once the alias was established, I dragged an old utility into it... 
It seemed to take a few seconds; much longer than it should have had
I just thrown it into the actual trash.

Next, I double-clicked the 'Trashcan' alias, to see what was inside.  At
this point, the Mac dies.  The first time it happened, I got a "System
Error -32" and the restart button.  When I repeated the experiment the
second time, the System Error did not appear.  Instead, I got a watch
cursor which I could move around, but not click/activate/do anything
with.  Only 'out' was to use the programmer's reset...

I was able to reproduce this with extensions on and off, and with my two
cdev-type programs (flowfazer and colordesk) installed and not installed.

Anyone want to check if this problem exists on non-cx machines?  I plan
on checking my fx tomorrow at work.  WARNING:  The first time my machine
crashed, it did so badly enough that all the color icons vanished, and 
I had to rebuild the desktop.  On the positive side, the item I had
thrown into the trash alias was still there, alive and well...

I'd love to know if anyone else can re-create this problem.  NOTE:  I'm
not involved in System 7 development at all ... just another user trying
to explore the new OS!
