Can't you make the opening a two stage process and use a notification when the 
window hasbeenclosed to issue the "real" opening?

I wonder if there is a delegate to the open dialog that has events for that.

Issuing delays to start a thread blocking operation at this point seems to beg 
for potential race conditions IMO.
