Hey guys, after I upgraded to Itunes 10.5 beta 2 on my Windows pc, and upgraded to iOS 5 beta 2 on my Wifi Ipad 2, Itunes is very laggy, and doesn't respond. Any fix for this? I've tried uninstalling it, rebooting it, reinstalling it, then reinstalling iOS 5 beta 2 on my Wifi Ipad 2, but same issues.
