ZBrush behaving really strange

I am using ZBrush 4 (Don’t know the version, there is not even an About screen) in Mac OS X Lion 10.7.1 and I seem to have several problems with it which is making it very unusable. Backface masking doesn’t work, I have to disable Multidraw in order to stop glitches on the movement of the cursor, there’s a random slowdown while moving the camera, sometimes keys are locking and I have to press them again in order to unlock, etc… So, its absolutely annoying to use it, I can’t continue to work on it. Whats up?

Please post a complete screenshot of the ZBrush window.
