I've had this problem with a Microsoft mouse.  I attribute it to the
surface the laser is reflecting on (wood with dark lines going through
it).  Surfaces that have repeatable patterns tend to confuse an optical
mouse, and will sometimes result in the mouse moving rapidly across the
screen.  Once you move the mouse a bit more, it will stop being confused
and return to normal.

So, I guess my point is: If you're using your mouse on a surface that is
not monochrome, try putting a piece of blank paper under the mouse and
see if the problem still happens.

You were right, the problem was a bad Dell mouse pad.  It has tiny
plastic grooves cut into it, which were confusing the mouse.  Thank
