After getting home, I finished putting together the computer I use at school. The day before yesterday I was using it at home when the mouse suddenly died — the scroll wheel lost its scrolling function for no reason and turned into a free-spinning wheel… I swapped in the old mouse from home, and it worked. ^_^ Yesterday morning, the mouse pad was so dusty that the optical sensor couldn’t track properly, so I tossed the mouse pad off to the side to cool down. Yesterday evening, the replacement mouse died too — the wheel rolled, the left and right buttons clicked, but it wouldn’t move. Looked like it had been hit with a paralysis spell… No choice — I went out that night and bought a new mouse…
