View Full Version : 2011 MBA leaves black bars?

Feb 10, 2013, 05:24 AM

I am using an external monitor with my 2011 macbook air. Sometimes when i move a window 'stamp' of the window in form of a black box will stay on the screen. It gets pretty annoying through out the day so i have to change my background picture or restart to remove the black boxes.
Is there anything i can do?
