Russell,

Yeah when it happens I'm never sure exactly where I downclicked and where I upclicked. I'm usually sure I upclick within the confines of the button, but only Windows knows for sure. *g*

It doesn't cause and data loss or even happen often enough to make me want to switch to Linux. *L*

>Yeah, that's my experience. I know that if I'd seen it in other apps, it would jump out at me as being a Windows issue and not VFP specific. Obviously, if you click and are moving the mouse and the upclick occurs outside the button, Windows won't recognize it. This is proper and by design. I haven't had any replies that specifically say that they are seeing the exact behavior that both of us are seeing and that I (and you) only see in VFP.
