I have a small problem with my 757 panel with the radios. I cannot manually tune the Comm and Nav radios. I can manually change squawk, but not the comm/nav. The little hand with the plus/minus sign shows up when I move the cursor over them, but it will not change frequencies. I remember a while back, I was able to do this with this panel, but then one day it just stopped working.
Is there something in the config file I can change to correct this?
Any help is appreciated.
