>I've been noticing a *general* clicking problem in VFP 5.0. The mouse down portion of the click is recognized, but the release is not. If as an example you click the x (close button) of anything, and the action is not fully recognised, then passing the mouse pointer over the object changes its appearance.. A second click continues the normal action. This is happening to me on buttons, close boxes, almost anything you can click.

It certainly is. Let's hope they fix that in 5.5 in March.
