Has anyone else noticed that, in Visual Fox Pro and Fox Pro applications, that clicking the "X" button in the upper right hand corner (to close the window), occasionally doesn't work the first time? It's the oddest thing.

You click the button, and it depresses (as if you are holding down on it), but nothing happens. if you move your cursor back over the button, it depresses again (without you clicking on it), and if you click on it THEN, it works. I've found this to happen inside the developement system, during design time and run time, and in my compiled applications.

Has anyone run into this? Any suggestions or tips?

TIA!
