>>It seems that with VFP8 (which I'm still using, and thus it's only VFP8 that I can speak for), suddenly native VFP tooltips only display for about 1 second or less, then disappear. I cannot find anything that would have changed things except for the occasional Automatic Updates from Microsoft.

>>Any idea what could be going on? Tooltips in other apps seems to work OK. Our VFP apps still seem to work fine, it's just a misbehaving tooltip issue. This happens even when I simply use the devel environment to create a simple form with a single button with a tooltip (i.e., no VFP timers going off in the background, etc).

It's VFP9 system variable. It does not exist in VFP8.
