Moving a window around wildly with the mouse makes it *stop* happen. But moving the mouse over different elements of the screen - or writing text in the web browser email window - seems to make it worse. Funky. It does "feel" to me like some bandwidth limitation, it has kind of the same behavior that I remember from the bad old times when you were pushing the video card past a resolution that it could really handle. But that can't be the case, this card has had no problems with this before. Linus
