If I fly in native P3d without the Rift headset, pressing SHIFT + [a number] gives me a pop-up window as defined in the aircraft's panel.cfg file. If I try this with FlyInsideP3D4 I note that a second screen appears on my monitor, with the appropriate pop-up. However, I have found that the pop-up may or may not appear in the 3D window, and it can appear apparently almost anywhere. Once I have it I can resize or reposition it with no problem, except that these windows appear to randomly reposition themselves.
Is this a problem for anyone else, or should I be doing something differently?
