The FS9 version, unfortunately
The 4.6.1.7. I've also tried the 4.6 and the 4.3.
Honestly I don't remember, but the only version i've found in my old storage folder was the 4.3, so I suppose I was using that one.
I've tried mouse and keyboard (even with the atc, that should be able to change the frequency automatically), but none of this worked.
I'll try to programm the radio button with FSUIPC4
I know, but the problem seems to be correlated to this.
I never though it was a FSUIPC issue, but i've read about the same problem with fs9 and it was fixed with an FSUIPC update, so here I am 8)
mmm, i can't reproduce the problem becuse now the radio panel is working :shock: I'll do some flight to reproduce the same condition of the first time i've encountered the problem!
The PMDG 737 for fs9 is not officially supported for FSX, but all gauges and dll working fine. :lol:
Thank you again for support!
