It happened again in the first level. This time I did not try to stop it and just let it run. What appears to be happening is the game is acting as though I have the move forward button pressed when it is not. When I do actually press the mouse button to move, it releases me back to normal. This does not happen in any other game so I'm assuming my mouse and drivers are functioning properly.

I'll check for a later version as suggested.
