Hello everybody,over years I have enjoyed this addon of PMDG, but right now the first (!) problem occured:I recently bought the Hat track (something similar to TrackIR) of VRInsight and tried to use it with the PMDG B737NG.Flying online on IVAO I tried to switch frequencies on the radio panel, but it didn't work. Sometimes, after clicking for many times, frequencies are changed but it takes a lot of time.Before you ask, my pc is more than capable of running the this addon.Disconnecting the hat track from the computer, the problem was not solved. Still, I am not able to switch the frequencies.Incidentally, I found out that the keyboard combination of STRG-K is send all the time to the FS. Removing this from the keyboardlayout in FS9 did not help.I also use FS2Crew PMDG Voice Edition, probably it could be the problem....Had anyone of you experienced such problem?RegardsSimon Schwenke

The issue could have to do with setting your default flight from a saved flight and switching to the NG. Always start flight from NG or default FS9 flight.

Hey,sorry for being so late in this post I started.I always start from the default FS9 flight and not from a saved flight. So that might not be the issue.As I posted this issue over at the FS2Crew forums as well, and I did some error checking myself, I will now try to reinstall and see if that helps.Anyway, thank you for your answer!Regards
