I'm wondering, why is it that when I play an MP3 on my Performa 6200CD in iTunes, that it only plays the mp3 and then isn't responsive at all? In some cases if I click pause I have to wait like 30 seconds for it to do the action. How can I fix this?

Running :

OS 8.6, iTunes 1.1 hacked for 8.6.

machine specs in my signature.

Thanks!
