But then I made a new user account on the same machine. That fixes it. at least with respect to the display in my laptop. I wish I'd thought of that sooner! At least I won't have to buy a new machine now.

I was careful to use just one monitor running during troubleshooting. At the start of this thread another monitor was connected at times, and that was suspected as being at the root of this problem.Just to be clear, and that is something I rarely am, does this issue occur when only ONE monitor is running?
I think you mean, "If yes..." You're right of course.If no, then I cannot think it is a LC issue per se, but rather environmental.

Yes, you're right, it was turned on. Now, I I'll check to make sure that feature wasn't causing problems. Hold on a minute... Nope! Seemed like a long shot, anyway.There is a setting in System Preferences > Accessibility under the "Cursor" tab that allows you to "Shake mouse pointer to locate", it does what you describe here, is that turned on?

Good suggestion.

I hope this helps.
The test stack works normally in the monitor, whether or not the two windows are aligned at the top in preferences:display:arrangement. I think I tried this before, and got inconsistent results, but I can't remember.
No amount of fiddling makes the stack work correctly on my laptop's display. I tried quitting LC, setting various display configurations, then unplugging the monitor and launching LC again. The test stack continued to work incorrectly on my laptop's display.
Nevertheless, that was helpful. I now have three ways of using LC. 1-display it on my external monitor, 2-Use it in my new user account. 3-Buy a new laptop.
Let's call that success!
There are two profiles for my external monitor in library: colorsync: profiles: displays.
I'm going to post this now, so I can log into the other account and check to see if those profiles exist in the library of my new user account. I'm guessing not, because I haven't plugged in the monitor when using the new account. They probably get installed when I plug the monitor in, the first time. I'll add an edit to this post, to describe what I found.
How risky do you think it would be to trash those monitor profiles in my usual user account?
There are also profiles for other monitors in that folder, some of which I don't recognize. I wonder if one or two of them are profiles for the native display on my laptop. Do I risk bricking my machine if I trash those? On the other hand, it appears they are for color syncing, so they may not be relevant.
Thanks again to all.

Edit: Those monitor settings do exist in my new user account, though they have never been opened. They can be edited with the colorSync utility. It's possible they are installed with the OS. I think I'll leave them alone, unless advised otherwise.
