All of a sudden I've been having weird problems with my MacBook Air. I've been using it a lot in bootcamp lately. It started with a lot of different problems, but they seem to be disappearing. So here is the last current problem. I get into my account and Finder starts, but it isn't responding. I have the option to relaunch it, but when I do it still goes back to it's not responding state. I've tried repairing permissions. I would really appreciate if anyone could help me.
