As a registered developer I've reported this issue as well as a thread on the ADC forums. I'm hoping to get a little more insight here. I downloaded the .1 update, wouldn't install on 10.8 SSD, took three tries for it to "approve". After restarting Safari, moving Finder windows, EyeTV, etc all stutter. "Console" reports nothing regarding this issue, occurs on new accounts, did all the usual "fixes", nada. Anyone else experiencing this issue? Thanks!
