After uninstalling the G1000 NXI version 0.14.0, the problem was still there …so in the end I did figure out what was the cause …a conflict with a custom livery I downloaded from flightsim.to called “Racing” …
With all the other “liveries”, the functionality to use the PC keyboard to enter FP, WP or a direct to destination works fine !!!
Thanks again for your help, very appreciated !!!
Have a nice day
