>Hi Ed !
>Thanks for your explanation, I'll try it. But are you sure that "anything that runs inside of VFP is going to be single-threaded". I've played with xceedsoft backup library (several activeX controls) and it seems to do background processing.

Then exceed is spawning off its own process so control can be released back to VFP. Hit ctrl+alt+del and go to the Task List or Task Manager. See if the exceed process is listed as its own process.
