Windowed mode: With physics and collisions on, I managed twice to get my car spinning out of control to the left!

Second time I even took my fingers out of the keyboard and the car just continued spinning as if I still pressed the up and left key. All that is missing is the smoke and sniping wheels animations!

In both cases I collided (1st with a another car, 2nd time with a wall). Bug occurred in opposite sides of the track (lower left corner and finish line corner).
EDIT: Forgot to say that if I click out side the game window and then return I regain control of the car and the keys start working like they should again.
Am I the only to have stumble into this one?
