OSX Version 10.8.2 (Seems to be the problem, a video driver issue some reports say.)

The project was actually just created in Prelude, zero content was added. It
seems when scrolling or if video is playing or even audio, everything crawls pretty
Updated to my OS to 10.8.2 and it has cleared some issues however, I think it could be
running much better. It seems to be a problem reported by multiple users of the newest
Mac OS. Doesn't appear to be taken care of though...
All in all I think it is a issue in regards to the OS. I've recently setup my desktop
for editing in CS6 my other machines are still CS5.5. This computer is also
the only to upgrade to the new OS. Was suppose to get rid of headaches!
