To start, I play Diablo 3 in Full Screen Windowed Mode, as I'm sure that has something to do with it. As I get to the log in screen, I minimize, and load Youtube. or the other way around, doesn't matter. Youtube freezes my browser. I switch to Diablo 3, and, if I managed to press "play" on whatever video I happen to get lucky getting to, it plays normally while Diablo 3 is the focus window on my computer. Minimize Diablo 3, and Youtube freezes again.
Anybody else having similar issues?
