Everything worked, but the screen was unresponsive. For once, I googled

Carefully drag the corner of a piece of ordinary paper under the edge all the
way around. Yeah, I was suspicious too, but it worked!

That's interesting, I wonder what other devices might suffer in the same
way?

I got a TomTom One GPS for ten dollars at a rummage sale, and the touch
aspect seemed flakey initially, but after charging and some use, all seems
fine. I got a PDA last year, and the touch screen (you needed a stylus)
seems unrepsonsive, I was wondering what might be involved, not that it
really matters, it was a few dollars and I have no real use for one.

So haul it out and try it. Surely you didn't throw it away...

How do the edges know which spot on the screen was touched? Was the bit
of crud in ONE specific place that somehow allowed the whole thing to
work, like a ground connection or something? Is the whole thing like a
required ground connection and a bit of crud somehow breaks that
connection? The website guy used paper; what if I'd used a tiny bit of
toothpick sliver or wire or plastic?

I have an older Lenovo laptop with a touchscreen that I rarely use; it
must have a frame. If it ever goes wonky I'll try it.

I'd rather not have neighbors. If I can see them, they're too close.
In fact, if I can see them through a rifle scope, they're too close.
