I recently bought the RXP GTN750 and was planning to use it for multiple aircraft. I am using steam XP11 and when I load into the plane the display doesn't pop up and I have to go into the plugins and open it. Even when I do that it pops up and is a black screen. It looks like all the buttons are registering that my mouse is over it but doesn't nothing. I have the engines running and avionics/battery on and still nothing.
