Hi Dennis.

>I then went to our dear VFP, opened up an existing project. Upon moving 'system windows' like the Command Window or Project Manager, an 'outline' of the moves along, albeit jittery, and lags behind the mouse pointer. The same behavior was noticed by a co-worker in his machine.

That's a known issue in Windows Vista and later. It only affects dockable windows. Unless you use dockable windows in your application, your users won't see it. It's a minor irritation but nothing too serious.
