Cannot enter any NAV frequency!!!

Hallo !

I have a very starnge problem here.
I have a PM Setup with GC, CDU and MCP and since the last updates of the CDU the NAV page lookes diferent. It is not posible to enter any COM frequencies anymore. Too bad to say that i cannot enter any NAV frequencies too. I see always the 108.0 frequency but when type in a different frequency it wont work. I noticed that if there is a frequency written to the waypoints in the route it is automaticlly used but i cannot manually enter it.
I have triedit with the default radio panel of the B737-400 but it wont work too. The frequency is always jumping back to 108.0.
I can see the "M" showing beside the NAV frequency that sould tell me it is manually tuned but it wont work.
Even when i change the settings in the CDU to automatically tune NAV frequencies there is no change at all.

Any idea with that issue??


Thank you all

Sorry...my mistake!

Problem solved, it was a wrong setting in the opencockpits driver config.

Thanks to all who read my thread
