Quake3 problem in Tiger

I've searched google on this and I've seen other people with the same 
problem but I have yet to find a solution. When I start quake3 on my 
powerbook, the game has the mouse cursor stuck in the center of the 
screen. It plays runs fine otherwise, but the cursor where the 
crosshair should be detracts from the game a bit. Other games 
(quake/quake2) run fine. The mouse pointer also tracks correctly in 
NeverWinter Nights.

Anyone see this and know a workaroud?

This is on a 15" powerbook 1.25ghz running Tiger.
