I don't know... ever since I've updated to 10.4.4, my PB hasn't been working too well. Whenever I check/delete my e-mails on aol.com, it always crashes on me every single time. And now, even when iTunes is closed, the icon in the dock mysteriously bounces up and down and opens the application. I end up having to manually close it, and about 30 seconds later, it opens up again. (I just closed it before writing the first sentence, and now it just popped up again) I have repaired permissions already; does anyone else have these/similar problems? It's driving me crazy!
