I don't know what the problem. I run version 10.3.9 with 1.25GHz PowerPC and 512MB DDR. I have a LaCie 160GB Firewire External HD. I just moved my music files to the LaCie for more storage space and now my music skips to the next song after 10, 20, 30 seconds, etc. I don't know what the problem is. Someone please help!!!!!!!
