SO far, it thinks it sux. I have to lift the mouse like 1/8th of an inch of the table in order to move around. However, I think this is just inherent with Laser. The navigation (back/foward) buttons don't work on Mozilla. None of the buttons except the normal two work in any games i've tried so far, FarCry, COD WTF, I have the most up to date driver as I can tell. What gives.
