So my firefox has frozen twice in the last day or so and ive had to force quit and restart, which I guess isn't a huge deal, it happens, but after the second time my spaces wasn't working all of a sudden. Neither of the 4 corners I use were working at all. I restarted and its working fine now, but I was just wondering if someone had any insight to this problem? I hope it doesn't repeat and I have applecare, but I don't wanna trek all the way downtown if I don't really need to. Also, my airport express has been cutting out on Airtunes quite a bit recently, but my wifi still works, whats up with that?
