Commonly, that means one of two things: 1. The switch is mechanically bouncing (though all switches bounce, and most input circuits have debouncing circuits to ignore that). As things age, the switch may bounce worse than the circuits handle. It's possible there may be debouncing software tweaks, but you're trying to work around a hardware fault of something that needs repairs or replacing. It's possible that squirting electrical contact cleaner into the switch *may* help (squirt then exercise the switch). Do not use RP7 or WD40 style sprays, they're corrosive, and will appear to work at first, but deteriorate into a vicious cycle of needing constant attention. 2. The soldering around the switch is cracking. If you can open up the mouse, you can resolder around the switch. This is a common fault for anything mechanical (switches, plugs and sockets) that are soldered directly to a circuit board. If this is the problem, and it's a favourite mouse that you want to keep, then soldering-in tiny flyleads from the switch pins to a less mechanically-stressed part of the circuit board will make a long-term repair. > Is this something that I can tune out with Preferences > Hardware > > Mouse in the MATE desktop? Or is there some other control? The double-click timeout in the mouse preferences is virtually the opposite of what you want (how *long* between double clicks before it stops considering them as double-clicks). If you were to try and adjust that beyond its normal range to handle your fault, you wouldn't be able to double-click any more. -- uname -rsvp Linux 3.10.0-1062.12.1.el7.x86_64 #1 SMP Tue Feb 4 23:02:59 UTC 2020 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
