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. Jon
