That's interesting, because it's true, this is a huge problem. Reminds me of a Flash game my son was playing the other day and when he would inadvertently move the mouse cursor out of the play area, the entire game would freeze and it would say in big letters, "Move the mouse back to this area." A good FPS has to be immersive, and that means full-screen, mouse-look, no browser chrome. So we have a ways to go still. But this is still a very cool demo of canvas.
