Lovely, looks like the left-click switch in my mouse is starting to go. It's started to let go while I'm still holding it down.
Considering that the adhesive on the skates has started to go too, I may look for a replacement switch and do some surgery on it, or may just say "fuck it" and buy a new mouse, considering that it's pretty much the cheapest logitech on the shelf... (They're the only ones I can find that are actually big enough to fit my absurdly-proportioned hands. With most mice, my palm and fingertips are both resting on the pad)
