Umberto,
In the middle of a flight, I put my headset on and decided to change the GSX audio output to it for landing. I opened up the GSX settings menu and went to the audio settings. I changed the audio device to the headset and clicked apply. Nothing happened. The button didn't change to the disabled color like it usually does. I tried to click Ok to exit and that did not work either. I had to click cancel to exit the dialog. Is that working as designed, or is it an issue?
Thanks!
