It seems the " -engine 1" parameter was all that was needed.
Cygwin/X now shows up on my new Windows 11 laptop, as it did on my older
one, with the saved session bringing up three xterm windows and all.
Giving me a richer experience and enabling me to work more efficiently than
when I had to start mintty sessions from the Window task bar.
Thanks, anyway, for your help, Jon.

Regards,
Erik
