Hi John,
You have seen right, after "window" parameters removed, GUI work again !
So i have success to save all logs ! (find in enclosed)
what i have been done is :
1) open MFS2020
2) choose an airport for departure, and then start simulation with A320
3) after simulation loaded and having take place in cockpit, I have open FSUIPC GUI and go into button and switches menu
4) first, I have rotate the working encoder to assign it to "AP_MACH_VAR_DEC", click on ok to save, and repeat the process for "AP_MACH_VAR_INC"
5) in second time I have rotate the not working encoder to assign it to "AP_ALT_VAR_DEC" and "AP_ALT_VAR_INC" with the same process than the working encoder
6) Nothing about the not working encoder seems to work after have tried the assignments
7) I came back to main menu
Thanks a lot for your support !
Adrien
