[Q] Does anyone have drivers/programs which give you "ballistic" mouse
response? The Microsoft Ballpoint Mouse driver has this sort of feature. The
faster you move the trackball, the more distance is covered by every mouse
tick. If you move the mouse very slowly, it might take several revolutions to
get to the other side of the screen. Move it quickly, and you're over with a
flick of your thumb.

[A] The file I've got is lmouse64.zip -- a new version of the Logitech mouse
driver which vastly improves on the one bundled with the Aero.
