Just started using the ATC in FS2004. I noticed after selecting a menu choice like "acknowledging ATC transmission" that the ATC menu window closes and disappears. I have to click on the ATC icon to pop up that ATC menu window again.
After selecting another choices like "tuning to a radio channel" it closes again. I then have to click the icon to open it up again. That gets tiring. How to I keep the ATC menu window open constantly!
Oh yes, I brought this FS on a lark and I've become addicted. My favorite plane is the Airbus A319.
