While in-game, no controls function. The mouse cannot be use to rotate my character or look around. W, A, S and D do not move my character, the stance change keys (C, X and Z) have no influence, the inventory is inaccessible. ESC does not bring up the menu. The main menu screen works fine, I have checked all the key bindings and run the game in windowed mode. Nothing works. To summarize, The main menu if fine, however, while in-game, it is as if my keyboard and mouse aren't even connected. I can only tab-out. The only way the game can be closed after joining a server is to tab-out and use the task manager to 'End Task'. This is not reproducible by others, only myself. I hope this is enough information for you.
