Worked great with Firefox until I started XMMS.  Everything was fine 
when I started playing an mp3, but it locked up hard when I switched to 
another desktop (had a Firefox window on the desktop I was switching to; 
it painted the Firefox widgets but hadn't repainted the webpage I was 
viewing before the lockup).

Looks like it's thread library independent too.
