I have no idea why, but suddenly my iTunes won't open. The little black triangle appears under the icon in the dock, but that's as far as it gets. And when I right click on that dock icon, the pop up menu gives me a "Force Quit" option instead of the regular "Quit". Additionally, at the top of that right-click pop up menu, it says "Application not responding". I've tried repairing permissions, zapping the PRAM, and even reinstalling iTunes 5.0. Nothing has helped. Anyone know what's going on, or how to fix it?
