Peter,

I was able to duplicate the behavior in VFP8SP1 on XP. I didn't reply because I couldn't come up with a decent work around. Other than to get rid of the "old" window technology you are using in there and do whatever you are really doing with another form instead of a define window.

>For some reason nobody replied. Anyway, I've done some additional research and have discovered that it happens in VFP7/WinNT and VFP7/WinXP, so in VFP7 (SP1), but no longer in VFP8 and VFP9.
