Re: Speaking of which,
The software I rely on thrashes the mousewheel/middle button.. bought a replacement after the middle button started bouncing/echoing, after a month or two the replacements wheel decided to intermittedly reverse direction (effectively, guessing its loose contacts)
Solution.. plug the original into a spare USB socket, and have one mouse for clicking and the other for scrolling..
I will eventually get to a place where I can get a third mouse, whereupon the two cripples will be put back into reserve.
