This has happened about 5 times in the 3+ weeks i've had my PowerBook. I would be using Safari, and I would open a new window and put in the website(it just happened when I put in amazon.com). The idle beachball icon would then appear, and then ALL of my Safari windows would close, and a bug window would open(the program has unexpectedly quit, report to Apple, etc.). Of course i've sent it to Apple. What should I do to fix this?
