Confusing Cygwin X / xlaunch issue

First, things work fine when I am using just my hi-res laptop display, or that
display plus a hi-res external display in "Extend these displays" mode
according to Windows 10. At present I am using a lower resolution external
display (becaue I am on an extended trip and it's what I have) in "Extend
these displays" mode with my hi-res laptop display. This seems to confuse X
(and also xlaunch?). Here are the issues:
When booted with the external lo-res display as the main display:
- xterm windows come up with a very large font.
- The X menu (controlled by .XWinrc) does not come up.
If I then change to have the laptop hi-res display as the main display,
without rebooting, and without restarting X
- The xterms still have a big font (I did not restart them, so no surprise)
- The X menu works (over on the laptop screen).
I then restart X,
- The new xterms still have the large font
- The X menu still works
If I then shutdown X, make the external lo-res display the main display, and
restart X,
- The xterm fonts are big
- The X menu does not come up.
Then, if I set the laptop to be the main display, reboot Windows, and restart
X,
- The xterm windows have the right size font (but start on the laptop and need
to be dragged over to the other display; they do resize appropriately there)
- The X menu works (but is way over on the laptop display).
Finally, if I change to have the external display to be the main one, without
restarting X,
- New xterms come up with the right size fonts
- The X menu comes up on the external screen (as desired)
If I shut down X and restart it (external display still main),
- xterm fonts have the right size
- The X menu does not come up.
It seems that, at the least, I need to *start* X when the laptop (hi-res)
display is main. I'm less clear as to whether I need to *boot* with it main
(I can try that later).
Is there an explanation for this? Should I be doing something differently?
Is there a bug? Thanks for any insight you can offer! Eliot Moss
Here are further details of my setup:
I use xlaunch to get my X windows going. The command in the Windows short-cut
that I click reads:
