Great!

Now we have screen-dragging too, but there is a minor problem: Although i'm testing it using 2 screens with exactly the same resolution and color depth, the screen becomes black for a second when i drag. Just like when i switch screens with different resolutions. Is this normal? I'm using a BVision. Also, dragging is not possible using the keyboard. (lalt+Amiga)

The problem also occurs even if i have only 1 screen opened.
