I've worked out the cause of the problem, and the weirdness of the apparent solution.
I broke both shoulder blades in a recent fall. In particular, I still can't raise my right hand onto the mouse pad on the right side of my keyboard, and there's no space for one on the left. So I put my wireless mouse on my desk above the left side of my keyboard pull-out shelf. When I reached for that mouse, my forearm was depressesing the CTRL key. When I tried the other mouse, a few inches away, it didn't. That explains the weirdness of one scroll wheel magnifying and the other scrolling, and then the first switching back to scrolling — because my forearm formerly dragging on my CTRL key has moved 1/2 inch to the left or right. Being aware of this problem I can now consciously take care to avoid it. One of the correspondents — I don't remember who — pointed out the relationship between the CTRL key and the mouse wheel — a relationship of which I was completely unaware — and that's what got me to thinking and carefully observing.
