Same here. I've had a small number of freezes; maybe one per week, or a little less than that. Several behaviors:
1. Freeze of the interface, but audio continues to play. Buttons don't respond, display won't really update, but some of it sometimes will partially draw.
2. Program freeze where audio stops *and* the display won't show at all.
I've had recovery from type 2, but only like 1 in 3 or 1 in 4 times. Type 1, audio keeps playing for as long as I mess with it (no longer than 5 minutes or so), but won't recover until I quit and restart MC.
