You're definitely right. I'm sorry for leaving that out. It's Knoppix version 6.4.4, which I believe runs lxde with compiz fusion (although I don't think the latter plays a role). I've been out of the Linux loop for quite some time (my latest Linux box had a 600MHz processor), so hopefully that isn't too out of the ballpark.
