After sending the message, set the defaultStack to the main stack before 
doing anything else. That might resolve most of the problem.

Also, it might help if you open the Progress as a palette instead of 
with 'toplevel' or 'go'. But if you use this approach, you should make 
all your object refs in the Progress stack absolute (e.g. put "of me" 
after each one) so its code will understand which stack should be changed.

Sorry - I'm out of time. Maybe others will chime in.
