If you open it up, you will probably find cracked solder joints on the legs of the microswitches caused by the switch not being fully seated in the board when it was soldered originally. So the leg pushes the joint away from the board on the down stroke, eventually breaking the glue bond of the copper to the board, and eventually the edges of the joint will fail from flexion. Visible with a magnifying glass quite easily. You get one click when the switch clicks, you get an up event when the cracked joint opens as your finger goes on down, the a new click when the joint comes back together on the release, followed by an up event when the switch itself finally clicks open. Hold the switch down solidly into the board while resoldering each leg, applying fresh solder and it should be fixed for a while, but the real fix is a new mouse. >Any ideas? >-- >Claude Jones >Bluemont, VA, USA -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules.
