Mine was running great before, but it took several restarts of my iMac after the patch for everything to get back to normal. I "think" the EyeTV software (which "was" set to start on boot) didn't like .2 very much because it seemed to hang things up for a few minutes at boot. The Magic Mouse 2-finger swipe quit working until the 3rd or 4th restart, but it seems back to normal as well.
