Whoops!  I'm sorry Eliot.  The one time the Win32 VM actually popped up 
a dialog window (instead of an in-image offer to drop to evaluator), it 
suggested there had been a VM problem.  I could never repeat the pop-up 
of that dialog window, though.  Thanks...  I will be more careful about 
my terminology.

Re: the 6.0 alpha image -- this becomes a catch-22.  :D  I was playing 
around with updating via trunk to see if I could get around the 
unaccounted-for removal of Context>>#inspectorClass present in the 
downloadable 6.0alpha image.

But now I see it is present after updating through trunk too.

May be time for me to cease and desist.
