Anyone else having this problem? Several times this weekend, my brother and I would be playing WoW. Everything would seem ok until we actually were 'logged in' and we started to play. My brother would just start randomly walking into walls and we both could no longer talk to anyone except each other. Anyway, the first time on friday when it happend I restarted my computer and it was working again. Today nothing I did worked. Anybody else having this problem?
