Thanks for the suggestions. I added UseFastTls 2, didn't help the stuttering/lock ups Setting the option to play sound in the background did help with the sound disappearing, but now I have another couple of problems. When running WoW in full screen mode, I can alt-tab back to my browser,email etc. just fine. But when I switch back to WoW, it doesn't go full screen, instead it fills the screen between the top and bottom panels (i.e. I can still see the panels). Not a huge problem, but as I think running the game full screen has sorted out the lock ups, I'd like it to switch back to full screen when I alt-tab back to it. If I use rotate desktop cube (ctrl-alt-left/right arrow), I can switch out of Warcraft to the next desktop, but when I try and switch back, the game has disappeared! I can still hear the sounds in the background so I know it's running somewhere, but it's not on any of the desktops. I'm tempted to just wait for the next Ubuntu release, sometime in June I believe, to see if that will help. I will probably be rebuilding from scratch as my install choices of disks/partitions etc. were not ideal initially. But I wouldn't mind getting to the bottom of this problem in the meantime. Thanks.
