I've no idea what started this happening either, if you move the cursor to the extremities of the screen it is like you are dragging the screen around up, down, left, right, any idea what I need to do to stop this occuring as it is seriously annoying me now, never seen this before.
I though maybe some kind of wallpaper issue? although the one I have has been fine for the last 6 months....
Thanks in advance
Pete
