I'd a mouse do similar on the right click button a few days ago, but that was a faulty mouse, a replacement cured it.
Yes, repeatedly. Including changing them a notch or two, testing, then re-setting. Still doesn't fix it.
I am now on my recently purchased 3rd mouse.
I am now thinking 'could it be incipient hard disk failure?' as my rust spinner is 10 years old, light home use, because when I dismount it to run the utility repair, that stops it for a few days.
But if run the utility repair while it is still mounted, it doesn't work.
Before anyone asks, it is 500gb, about 1/3 empty, so lots of space.
All suggestions welcome!
