turn the driver settings up to max. A normal mouse can cross the entire screen of a standard widescreen monitor in about 1.5 inch square movement. When the settings are very low, you actually need to lift the mouse off the pad over and over to go across a screen, but pro gamers (not chess, really, talking action games) usually have it so very sight movements give big results fast. Mine is set up for this kind of movement and its a wal-mart logitech optical sensor, 2 buttons and a wheel mouse. There are fancier mice with programmable buttons and all sorts of junk but I am old school :)
Be warned... if you are used to a pokey, heavy handed mouse speed, it takes time to adjust. Ive used barely touch for so long that its easy now but many people using my machine freak out and can't control it...
What mouse do you have? How many DPI? I think my mouse is slow for bullet.
