Hi,I have osted a problem with the R4D Radio panel as well under CAL2024. I have yet to recieve any concrete resolutions and hope to do so soon. II have tried reloading several times in windows 7, FSX. I have since purchased the DC3 version from Just Flight 1 and it will only show their great inst panel in virual cockpit, but does only show the DEFAULT DC3 panel in 2D. I am getting to think it may be associated with either windows 7 or the dual core set-up. My thoughts only as I am not a PC wizz. I just wanted to let you know there is another individual with the same issue.CAL2024
