A lot of knowledge here so i'll try here . I thought maybe it had some thing to do with my Go-flight modules but i disconnected it and it's still the same -- with all aircraft . I put in a code say 2200  but as soon as i put them in they go to zero right away and won't hold the  digits. As far as i know i didn't play with any thing and totally stumped on this and i don't really want to go on Vatsim with this problem . Any one ever hear of this ?  

What airplane? Have you contacted go-flight support?

No i disabled it and it still does it on all of them,(general aircraft all pay ware  A2A Phenom ect. but maybe i should contact them just to see.  thanks 

Sounds like something is overriding your inputs.  Do you have some sort of program that simulates a copilot and puts the copilot in charge of the radios?
