Thanks for the reply. It finally started working, but if it happens again I will try your suggested trouble shooting steps. Thank you.
I tried reinstalling everything: latest reality re-ran xplane update, re-ran reality xp update, re-ran the RSG windows installer. It still didn’t work. Finally as a lark, I tried removing and reinstalling the pen mount drivers for my gtn650 and now it works. I hadn’t done this before, because if you try reinstall the penmount software over an existing install I got an error hat said cant reinstall without deleting first. So I did it, and now it works.
Could be a coincidence, but it’s working. And to your point this is the first time that I can exit xp and come back and the windows are still where I left them from the previous session. Even when it was working before, I would always have to reset up the windows. Maybe a file corruption????
thanks again for your help
