Win!
Since one of the early heavy rains, which entered the house via the window near my desk and assaulted my Kensington ExpertMousePro the top-left and scroll-wheel-depress buttons have both been producing the button-code of both of them - mostly a minor annoyance because wheel-depress wasn't bound to anything.
This evening I finally got sufficiently irritated with it to fix the problem (a short between two legs of the IC) with a screwdriver, some muttered swearing, and a stanley knife.
