Hi,I purchased the 737ngx about a week ago and fly on VATSIM a lot. I use squawkbox 4 and when I change the transponder mode to squawk normal in the pmdg, it doesn't change sqawkbox to normal.I've had the pmdg 744x for almost a month and do not experience this problem when I squawk normal from the plane's transponder. Squawkbox changes to normal.I'm running FSX on a 64 bit windows 7 professional platform and I have a registered latest version of FSUIPC.Any idea if this a pmdg, sqawkbox or operator issue?Jeff SmithSent from my Kindle Fire using Tapatalk

I don't know, I have the same problem though but it's not a huge deal so I just put up with it. Hope someone can figure it out :)

Oh is this function available for FSInn+NGX? I had never heard about this.
