  FYIO: Description of why the new mice jump into postions....

  The old mice used to have no brain's what so ever, so the pointer only
moved when the computer had time to pay attention to it.
  It is my understanding that the new ADB mice kinda "know" when the last
time the computer asked for a postion, and they "keep" all of the movements
since the last query.  So when you move the mouse and the Mac doesn't have
time to look at it the ADB mouse keeps on adding movement until the mac 
asks it for the new postion, then when the mac finally gets around to talking
to the mouse it realizes the mouse has moved quite a distance and updates
the screen to reflect that, the mouse "jumps" into the new postions.

  I don't like it either, but I hear you get used to it.
