Morning,
First put-in didn't work, thus i reinstall the original 4.969 then put the b dll version and the error window appeared, say yes and FSX start.
I choose basic C172, can open FSUIPC, name profile "Monomoteur" and configure axis. The plane fly correctly. Cant create another profile. I leave the fly and takeoff again, the profile is keeped.
Shutdown FSX and load it, Same flight conditions. "Monomoteur" profile is charged, can modify it, cant create another. Thus shtudown and reboot PC. No profile charged. Can create new one.
When you stop the fly and change plane, each time the last used profile is charged. Even when you take a plane with existent profile. Cant create another one. Need to exit FSX and reload to empty the profile. Sometimes needed to click twice or more to open FSUIPC.
May be a checkbox "exit profile" near "specific profile" could help.
