Hi Has anyone else suffered with screen flicker and the black-out with the newer iBooks? My prev 12 and 14" had no problems but this 12" keeps doing it. Apps are still running fine behind an unlit screen. Closing the lid and re-opening brings the screen back - for now. This sounds like the dreaded trapped cable in the hinge problem that has been discussed on some forums. A call to Apple is on the cards.... Matt
