it seems simpler than that. We tested another mouse and it worked much better. So it's probably the wire that has false contact.
Mice do wear out. The cable, the connections, are subject to metal fatigue. Fluff getting into optical sensors can make them erratic. Buttons wear out, the soldering around the buttons goes bad.
I've had several PS/2 mice, and I think a couple of USB ones, where the computer didn't seem to supply enough power to drive them, or was giving them electrical noise, and they'd frequently go whizzing all over the screen madly clicking on things. On a long cable, or plugged into front panel sockets they'd do this very often. But plugged straight into the motherboard socket they were usually fine.
I have at least one mouse that rapidly goes into a power save mode, and is repeatedly logged as disconnecting when you leave it idle.
I have been using a Kensington trackball for years, and except for wiping off the ball and wiping up the inside of the base every once in a while, it is very reliable, and of course, it takes up no extra desk space, since it doesn't have to be moved around. You should try one! (I have the cheapie, with only two buttons and no scroll--you don't need a scroll wheel with a trackball. About $25, if I remember.) Three computers, three trackballs.
