Right!  Just updated my cvs, recompiled and when I now hit F3, 
even while the mouse is in control mode, the mouse pointer is 
re-centered on the screen.

I tried what I suggested just above and found that the controls 
were re-centered, along with the mouse pointer.

If you've moved the mouse around quite a bit before hitting F3 
then it's likely that you'll have hit the control limits at some 
point and then, when the pointer is re-centered, the controls 
will have an offset.
