For some reason all of the sudden right click stops working until I hit the enter key. Also after loading a save game or looking at the map or hitting esc to go to the menu my character jumps up and the right click button goes back to not working until I hit enter. I just got to the bank mission in thief 2, why would this just start happening now? It seems to be going on in all the older saves now too. Jumping after looking at any menu is making the game unplayable.

Also I seem to run all the time now instead pressing shift to do it, I can't seem to walk.

Restarting my computer seems to have fixed it, don't know why it happened to begin with though, really odd.
