I accidentally did a save-and-exit from the world menu while a debug window 
was active.  When I reentered squeak with the saved image the debug window 
came up as expected.  But I can't exit the window.  If  I try squeak hangs 
(not in a loop - just no response from squeak).  If I resize the debug 
window squeak hangs.   If I "proceed" in the debug window I hang after an 
error message appears.  I can minimize the debug window without causing 
problems.

I can fileout my changes and start my image from scratch but when I fileout 
all my variable names get renamed into simple t1, t2, t3 names.  I sure 
don't want to try and support my code after being mangled like this.

I also tried the world->changes but I keep getting errors so I don't think 
I can back out the recent activity.

I can open individual methods to recover source but this would take many 
hours to do since I have so much code.  Is there a way to fileout that 
preserves variable names?

Does anyone have any suggestions?  I'm running on windows at the moment.  I 
may try and open the image with OSX and see if I can recover from a 
different VM environment.
