..specifically, of course, with CS 6?
I'm truly sorry that's happening to you, but thank you for letting us know. By chance, did you make a partition for 10.8 so that you can go back to Lion, or whichever previous OS X you were using?
I've had no problems so far with any of the CS6 applications although I haven't had time to do extensive testing.
Adobe posted a Q&A where they said they hadn't identified problems with CS6, CS5.5 and CS5 in Mountain Lion.
