>This worked for me, too. But does that mean that each and every time I want to run the debugger, I need to issue a CLEAR DEBUG before working with it? Is this any better in VFP 7? I personally didn't get these problems until recently, and a complete reinstall of windows & then VFP didn't help at all.

No, but if you will experience GIF, this command will help. Or deleting FoxUser.dbf
