Since the update on 30/7, frequenty (sometimes 5 times in a row), I login and appear in the room I logged out in, but nothing works. i see the "cursor" dot, but cannot move. Mouse does nothing. no keyboard action does anything, e.g. tab doesnt bring up inventory, esc doesnt exit to lobby. In short, same as mouse and keyboard being detached. Have to CTRL-Alt-DEl and kill the process. My friend with win 7 has the same problem. Some servers seem more prone than others. We were playing hardcore mostly, but not experimental. Not sure if same problem on regular.
