Ok Guys
This is it. I hope.
Mike I fly Vista/FSX
This morning I went into Flightsim.com and found that there are a further 2 files L049A302.zip and L949A303.zip.
One of them corrects minor panel problems the other changes the size of the Radio Panel.
Downloaded and installed both.
I have now an updated radio panel including the GPS/Nav switch and in the main aircraft panel at the bottom is the new position panel for Altitude selection and switches for AP NAV APR etc.
Have to go fly it now.
Hope that this info helps everyone.
I went into Flightsim.com....search files...FSX Constellation and all the files required were listed.
Best regards
Roger
