I've tried to run DiskExpress II in automatic optimization mode on a volume
where I run ParcPlace Smalltalk-80 V2.3.  It *seems* to cause Smalltalk-80 to 
fail with "Smalltalk unexpectedly quit" followed by a system error.  

I say *seems* because immediately after I installed DEII, I began to get these
errors.  After three failures I manually optimized the affected volume and 
turned DEII off.  No more problems and a noticeable performance improvement.

I will continue to use DEII manually until I switch to V2.5.  Then I'll try it
again.
