Yes, I meant lock my account. If you don't recommend sleep or hibernate, what do you? Just keep it on all day & shut it down at night? Just curious. I'm always interested in learning new things.

I'm going to run a few tests in order to let you know what isn't causing the problem, & I'll get back to you with the results.

So do you just keep your computer on 24/7? (Hope that worked. My first attempt at quotes.)

OK. Here's the scoop after my experiments. If I either manually, or let the computer put itself to sleep or hibernate, my Fences are intact when I power up the computer. Evidently, the only time the Fences are playing "musical chairs" on my desktop is if the hard disk is turned off & I power up the computer before it enters sleep or hibernate mode. Follow me? 

Thanks for all the help!   

Guess what? I found another problem causing the icons to move around. It took me awhile to pin down the cause, but luckily I use a lot of sounds. There is a scheduled task called UserTask-Roam that is causing it. It's located under Windows, CertificateServicesClient in Task Scheduler. I did a Google search but I'm finding a lot of old stuff rather than Windows 10. Figured I'd see if you, or anyone else, knew whether or not I could disable it before I did any more searching.
