Hi all, I recently got a MBP (i7 2.66ghz, 8gbs ram, 7200rpm hard drive) and since I got it apps seem to temporarily (like for 10-15 seconds) freeze (only 1 at any time normally) and i'll get the spinning beach ball thing. Even if I only have say 1 app open (like safari) it'll hang up for 10 or so seconds randomly. It happens say maybe once or twice every hour (but having said that i've used it hours at once with a lot more than one application open and it hasn't done it) on various apps and I don't know why. Is it normal? I wouldn't think 1 app such as safari or itunes running should do that? It's not a problem(?) that bothers me really, I just want to know if something might be wrong? I've only had the notebook for a week so far and it's my first Mac.
