Vlad,

>You can use both debuggers in the same time. But this not of much help, since VFP is single threaded. So, while you're in the COM method, VFP is not running. Or, better said, you can't have both VFP and VC++ code running in the same time.

Yeah VFP isn't too cooperative in this environment. Especially when it's screen won't paint. I tried launching another VFP session while in the VC debugger from the start button but all I got was a splash screen, it didn't finish starting up until I shutdown VC.
