3 possible problems:

1) Bad connection in the mouse "tail".  Pull more wire through the strain
   relief, cut out bad wire and resolder connections.
2) Bad photoelectric components (unlikely).
3) Tolerance problem with the slotted wheel and sensor.  I had this problem,
   leaned on the components (to realign them slightly), resoldered the
   connections, and it has been working fine now for 3+ years.  (you can lean
   on the components while things are opened up and live to check out this
   possibility)
