Why should I have it on? I always have itunes, mail, safari, ichat, and microsoft word open and its just another app I have to scroll through. Right now my computer is fine, I reinstalled the operating system and it is ok. Right now I am seeing if quitting it is the problem so I quit it and I want to see if it will freeze again. My question is, is this the problem? (Quitting the finder) Or is the problem of all these servers air mouse server, airphones server?
