Just listening to my mp3 collection, which was working fine if i remember correctley previously. The sound keeps going off and then back on. Like the CPU cycles are being eaten up by another program for a moment.. but i had Activity Monitor open and the CPU was hardley being used. Whats this about? Im using iTunes 5 and i dont have many other applications open (FireFox, MSN Messenger) but it can go for a while and then suddenly 'blanks out' and then carrys on. But just now it was doing it almost every minute and was starting to become very irritating. This is a pretty simple task to ask of any system, if its about 'priority' how do i tell OSX to give priority to iTunes?
