since i have installed iTunes 4 and QT 6.2, my computer has "been on the fritz" it is only recognizing a few peripherals and cds occasionally. the system is locking up at random times, and when i try to log out, at least 75% of the time it locks up in the process of doing so. i am running a 400Mhz G3 slot loadin iMac with 10.2.5, and it won't recognize my new iPod! I just got it friday, and was able to sync it friday, so I got some music on there. PLEASE HELP ME!!!!
