Photoshop's clone stamp tool disables my keyboard.
Ever since I installed CS5.1 whenever I use Photoshop's clone stamp tool it disables my keyboard and I have to restart my computer to get it working again. I have talked to Adobe, received new software, reinstalled it multiple ways, worked in safe mode, worked as another user, contracted an "expert." But the problem persists. Adobe says it's an Apple problem and Apple says it's an Adobe problem.
Any ideas or helps?
