I had the exact same problem on a P4 1.4g Win2k sp2.

>>I have 3 applications in production with VFP7 sp1. I never had a crash in production but in design time I have crash every day in form design. Il look like intellisense is causing the crash in my case.

>I've had some problems. They're mostly connected with the debugger being open. Further, it seems that Intellisense slows down dramatically (PIII 933mhz/Win2K Pro SP2) when the debugger is open.
