I've been using ML since yesterday and am really impressed. Haven't had any problems with it but I am noticing a bug in Safari. When I click on a video to watch in YouTube, it plays for a little and then the page refreshes. It's done this to every video I've tried watching. It's extremely annoying and I have no clue what's causing it. This never occurred on Lion. Anyone else with the same problem? Or know of a fix? Thanks!
