I'm thinking that maybe losing mental prowess may be a feature of aging... I was getting SWMBO's laptop computer up and running for a trip to Mexico, and couldn't get the wireless optical mouse to work. It would recognize the button clicks, but the cursor refused to move.

After a bit of fussing and mumbling on my part, SWMBO came over and suggested that "Maybe it would work better if it weren't on a glass-top table?"

Doh!
