Surprise and shock!

Absentmindedly, I put my finger on the stiff plastic room card I taped over the VAIO's touch pad at the start of my shift and started to maneuver the cursor. Looking at the screen, I was not happy with the cursor's performance, until I remembered, "Oh, well, I've got a card in the way," which led - about a second later - to the realization that the cursor was moving, erratically, even though my finger was not in contact with the touch pad!

I repeated the experiment, this time being very careful not to exert much pressure on the card (it's not the thickest card in the world, but not the thinnest, either). The cursor movement degraded, but did not disappear.

I hope this has something to do with local conditions and not with deterioration of the hardware.

Cheers...

Could the sensitivity be changed from the driver settings?

The only driver setting that made sense to change was the sampling rate, which I dropped from 100 per second to 20 per second. I don't notice any change in performance, though, but haven't had to do any heavy-duty typing the past day or two, either, so it's hard to tell if anything I'm trying to do is having an effect. The whole thing may go away simply be leaving the area, if the phenomenon is related to humidity in the air.
