I thought I'd mention some tactics that have yeilded mixed results.
I swapped the left and right microswitches, don't use the right as much. Grin.
Unsoldering and rotating the switch may load the internal membrain differently. (Have not tested this)
I ordered replacement swiches, they looked the same on paper. The switches were only slightly different, but the mouse was never the same.
I think Commodore contracted mice from manufacturers from around the world. There may have been several different microswitches.
