>Hmmm . . . that's interesting. I don't remember seeing it in any other apps (I use Outlook all the time) and I was thinking it had to do with the non-standard way in which VFP handles windows. Are you saying you see this exact behavior where the button will depress/undepress as you move the mouse back and forth over it (without clicking)?
You betcha. I do tend to see it more in VFP than the other apps, but then again, I spend much more time in VFP than the others.
