I will try WSPR-X and see if it will run tonight. Occasionally it
will go a few hours without crashing but more typically it is a few
minutes.

I installed Markus new batch file and the associated utilities
today. It seems pretty simple. All went well until I changed my
Windows default sound devices to make it work. At that point every
application involving sound ceased to function. I think the issue is
that selecting different default devices for some reason caused
Windows to re-enumerate every sound input and output device! Somehow
I am not too surprised. Windows is a pain in the butt!

I could probably get it working by changing the default devices and
then reconfiguring input and output devices in all my sound apps...
two instances of HDSDR, five of WSJT-X, five of SpecLab, SlowJT9,
and a few other odds and ends. That would be no big problem, but
from time to time I would have to change it all back, as there are
other things which require the default devices to be as I have had
them all along. Oooohhhhh...

WSPR-15 is very interesting, but it's not quite interesting enough
at this time for me to do all this reconfiguring periodically.
