I am having an issue with the radio comms pop-up window whereby it always pops up behind the main P2A window and there is no way to move it. I can see the icon on the taskbar but clicking on it does not bring up the radio comms window.

I do not experience this with the Nav radio window. What could be the problem?

Sounds like it's lost on a phantom screen.  Here's how to get it back:
1)    After clicking the Stby Com Freq, Hover over the P2A icon on the Taskbar. There should be multiple windows and one is the Radio Freq window
2)    Hover over that window and a larger thumbnail of the window should show
3)    Right-click that larger thumbnail
4)    Select Move
5)    Hold down the Right Arrow key on the keyboard until the program comes into view
6)    If that doesn’t work, hold down the left arrow
7)    Once the window is in view, use the mouse to move it to the desired location.
😎  Shut down Pilot2ATC so the location will be remembered.

Thanks so much, Dave! All's well now...😁

I have the same issue Dave, the window is stuck at the edge of the screen and I cannot drag or expand it, I can X it out tho :) when I hit the red edge (cross)
