With out problem I installed PMDG-747 X. One item is in question. When I opened COM panel radios are not on, including Transponder and Timer.Did I forgot to click some switches??Please advise.Sanal

I remember this coming up right after the 744X came out.. I had the problem too. In my case, it was probably a font file... don't remember exactly how I ran into the trouble but a reinstall fixed it.This assumes you've got everything powered, just no digits in the numeric displays.

Thanks for your replay. I reboot the PC and reopened the 747, Radios were on. I hope it will not disappear again.

I'm glad that worked, and after you mentioned it I remembered that's all I did too... just a reboot. Sure miss my memory, now where did I put it?
