4) Keyboard bug - that happens, not terribly often, but enough to annoy. When you're just running one client, you can alt-tab (or windows key, if that's your OS) out, click on the top bar of your session, then get back in game and all is well. Although I've noticed when boxing, that fix works until you slt-tab between sessions again. Once you get back, you'll be KB bugged again. I just get to a safe spot and re-log.
That's what I was thinking of. Sadly, it didn't help me. Maybe it'll help other though.
