Hi, Can anyone explain to me why my Itunes always freezes when i first open up (and sometimes even when my computer has been used for a while during the day)itunes, i try to access my music or change a track and it freezes on me, the only way i can get back to where i was is to shut down my computer entirely and open it up again. Sometimes, it happens three or four times which means i have to keep shutting down my computer and it is annoying. I am trying to purchase a track from itunes store and have tried 3 times this morning and each time it freezes on me.....help! Thanks, JoannaB
