So far I never needed the PS Forum, since all was good with my CS.
Now, that I am using CS6 (not CC!), I have this really weird issue, that I never encountered before: When I use PS, ever 5-10 seconds the App is "thinking" and goes into beach balling for 3-5 seconds. It does it constantly. Of course, it's impossible to work like this, if you have to watch the ball spinning all the time.
Any idea, what could be the reason for this odd behaviour?
