Mouse behavior with Q-rotate seems odd.

It feels a bit weird that the mouse cursor still moves when you hold Q to rotate. One of the side effects of this is that I can't do a full 360 degree rotation without stopping, moving the mouse to the center of the screen, and starting again. I like doing quick spins of the camera and with the mouse cursor moving I can't do that (since the spin halts when the cursor reaches the screen edge).
