Ann, I've found that to be a sign that the switch in the mouse was not 
properly soldered in, leaving a small space under it, which in turn means the 
solder joint and the foil of the pad can be carried away from the circuit 
board by a thou or 3 by the pressure of the switch being pushed fown into 
solid contact with the pcb, and eventually either the copper foil breaks, or 
there is a hairline crack in the solder.

The sequence then is that the switch closes with the down stroke, the joint is 
pushed apart so its silently unclicked for the duration of the push, then 
when the finger comes back off, the crack closes causing the 2nd click, and 
finally the switch itself unclicks.  Effectively a double click in double 
time.  New mouse time, or get out the controlled temp iron and re-solder it 
around all the switches.  I like to use a silver bearing solder for that as 
its much stronger physically than the usual eutectic blend.
