See attached photo. I connect the macbook pro (15" early 2011) to the 24 inch cinema display with the lid closed. Then if I open the lid and then close it again, the desktop becomes this. If I open the lid when no application is open and then close the lid, this problem does not occur. If I power up the macbook and type in the password when the lid is open, then this problem does not occur if I then close the lid. It only occur if I open and then close the lid if there is any open application on either the macbook display or the cinema display. Does anyone have similar issues and know what is the reason? Thank you!
