iTunes refuses to stay closed on my Windows XP computer. I'll close iTunes, it comes up with a dialog box telling me it's "Savings iTunes Library", that'll go away in a few seconds. About 30 seconds later iTunes reopens by itself. It repeats the close and reopen cycle anywhere from 3 to 20 times before it manages to stay closed. Any idea what may be causing this? I don't know if this is the right place to be asking this, but I don't know where else to put it. Thanks for any tips or advice.
