The damned thing hasn't worked right since. I've essentially shorted out my mousing surface until the condensation inside the case dries out, which makes doing anything on this computer a real nightmare. Hence the somewhat abbreviated Link Salad this morning.
It's not like I haven't had this exact problem before. Last summer, while staying at a friend's house, their cat got on my lap while I was using the computer and groomed my fingers and thumb so excessively that I unthinkingly got cat spittle all over the touchpad. It took the better part of a week to dry out from that. Having learned from that, you'd think I'd be smarter.
Of such small indignities is the world made. In the mean time, perhaps I need a touchpad cosy.
