Turns out, there was an Unrelated Issue, all the way back when I installed
Stretch.  I made an /etc/fstab error, causing me to not have a Swap
Partition.

So I had a Memory Low situation, causing programs on one Console to stop,
when I switched Perspective.

When I fixed my Memory and Swap errors, my problem is solved.

Sorry for the length of time between Replies:  I'm pretty busy.

And thank you, Jonathan, for putting me back onto troubleshooting the
actual issue.

I plan to learn SystemD as best I can.  It's here to stay, so make the best
of it.
