ITunes (v7.02 running on OS 10.4.8) hangs upon opening, eg wont fully open but icon stays in dock with tag reading, application not responding. iTunes will not respond to multiple attempts to "Force Quit", in that when Force Quitting from the Finder it shows in red as not responding, disappears as it should when I tell it to Force Quit, and yet the icon doesn't change in the dock and when I go to Force Quit again from the Finder it is back in the list again as not responding. When attempting to Force Quit from the icon in the dock, nothing happens. I go to Activity Monitor, to find the process ID for iTunes but it's not there, i haven't tried using terminal mostly because i don't know what to do there. The problem is intermittent. Occasionally it will go away when multiple utilities are run, preferences deleted, etc., but it always comes back. This issue forces hard reboots of my G4 powerbook (since I can't shut down or restart because the Finder hangs on the fact that iTunes will not quit), all to no avail. Otherwise, everything is running fine. I have two main questions: 1) How to fix this specific iTunes problem? 2) How can I force iTunes to quit so that I do not have to hard reboot my computer? Thank you so much!
