Hi, if I use my screen recording software Voila while playing Minecraft then once in a while the movement-key get "stuck". I have to press and release the key again to get it to stop. Probably the release event is lost.

When I release the 'w', 'a', 's', 'd' or space the avatar should stop moving...

What actually happened was that sometimes, not often but sometimes, the avatar is still moving after releasing the key and I must press and release the key again to get it to stop. Pressing other keys, even esc, does not stop the movement.

Steps to Reproduce:
1. Start the recording software Voila
2. Run Minecraft, press and release 'w' often
3. Sometimes, not often but sometimes the movement forward does not stop even after releasing the 'w'.
