Sure. And I can imagine how irritating and distracting it must be. Would it be possible for you to record a small video of this effect? Or do a screenshot for me? Just so I have a clear understanding of how it looks if others get the same problem. If it is not too much trouble, please email it to me. My email is the one sending you your activation key.
Another thing: Are you by any chance on a touch screen laptop? I mean not using a Wacom Cintiq or similar external tablet?
