Well, it seemed to mostly work okay on my ride today, though it 
autopaused once when I was NOT stopped and also popped up a 
submenu a couple of times when I had not pressed the touch screen.  
This latter could possibly have been from a drop of sweat landing 
on the screen, I suppose.  No idea about the stray autopause.

I do wonder if the thing got too wet when riding in the rain a few 
days ago, and is getting gradually better as it dries out.  Who 
knows.

Yeah, I thought of that but the last firmware update was some time 
back--many months.
