I Recently downloaded some new apps for my touch via the itunes app store on my iMac, i went to sync my touch and all of a sudden when i plugged in my iPod iTunes quit. I relaunched iTunes thinking it was just some 1 time glitch. Now anytime i launch iTunes i dont get the window at all, just the icon in the dock saying its running. and the taskbar at the top with all the iTunes menus. Anything I can do to fix this? I have already restarted my iMac and have tried to launch iTunes without my iPod connected..
