Hi, whenever I press a button on the pilot2atc autopilot window using xplane 11 the screen jumps back to the pilot2atc main screen. I have the OnTop button green but it jumps out of the program when I press VS, ALT, NAV, etc. What am I missing?

You should have OnTop button pressed on both the AutoPilot and main P2A screen.

If you are using XP11 in Full Screen or Full Screen/Multi Screen mode, anytime you click on XPlane, P2A will disappear, even if OnTop buttons are pressed, because XPlane is controlling the screens, not Windows.

In Win10, you can press the Windows Button and P2A will pop back up.
