I use my MBP 15 (late 2011) with 24" Apple LED Cinema display in a clamshell mode. After disconnecting external display, and opening display, it shows horizontal shifted bars, so it becomes completely unusable. Have to hard reset laptop. Any hints on how to resolve this? Thanks.

MacBook Pro, OS X Mountain Lion (10.8.2)
