Twice today as I am sequencing songs in a playlist the system locked up with a note on the top of the screen "buffering". It only seems to happen after I have been working on the playlist for a couple of hours. The lockup occurs as I click on a song to play and then it says it is "buffering..." and it is time to reboot MC. I am running XP Pro on an Intel board. Both times I have rebooted the system as well.
