Ive had this problem with other pop-ups from time to time and could never figure out what caused it. On the C-123, when I select a pop-up (in this case for the Radio's) and it comes up on the main screen (I have two monitors), I'll resize it and move it to the second monitor. . .9 times out of 10 it moves with no problems, but sometimes I get one that goes blank (dark) and I get a flickering "progress icon" that flickers constantly until I close the pop-up and even then it may remain for the entirety of the flight. Even if I move the pop-up back to the main monitor it will remain dark. Closing and reopening is useless as once it goes out on me it remains that way and I have to restart the Sim to get back to normal.
Anyone else ever have anything like this or know why it happens?
