I wonder if the IDL Bridge would help in this situation?
(IDL_IDLBridge object). The idea would be to run the progress
bar in a separate IDL process. I really have no idea if you
could communicate with the ProgressBar object over the bridge
in this way. But since it would be running in a separate IDL
process, it might solve the "update" problem. On the other
hand, it might also cause a world of problems on its own, so...

Cheers,

David
