  After fixing a jillion of them mice, I can tell you the problem is most
likely in the cable itself.  Right where the cable enters the mouse, it tends
to breaks the wires right there.  You can take the cable out of the mouse, and
then take the strain relief and slide it back 3-4 inches towards the end that
plugs into the computer.

  When this is done, cut and strip away the sheathing from the wires inside and
one at a time tug on the wires semi-forcefully, and when one of the cables
stretches and the insulation breaks, you've found the broken wire.  Now you
need to re-splice that wire, and put it back together.  Good luck!
