In years past, the mouse double-click for a single click syndrome was
caused by the pushbutton switch in the mouse becoming unsoldered, as
in a microscopic crack in the solder you had to use a strong glass to
see around the switches pin in the puddle of solder. Holding the
switch solidly against the board and resoldering fixed it right up.

Not for folks who don't know which end of the soldering iron gets
hot...

What was happening is that the switch would close and send the event,
but the finger then pushed the switch down against the board anotheer
thousandth, causeing the pin to rise slightly on the bottom of the
board, breaking the solder connection, which sent that event as a
button rise, and the situation was then reversed as the finger came
back up, giving 2 full clicks for one push.
