Hi guys, In a bit of a panic here. In the past few hours (after multiple restarts) my mac's applications keep freezing. Mozilla, second life, finder, iTunes ect. I don't know why they are doing it, but I get the beach ball on one app, then i click on the window behind it, then that freezes, then the entire computer freezes for about 20-30 seconds before returning to it's normal state. This has been happening ever 5 minutes or so. Can anyone offer any ideas? - Scott.
