Thanks for that Mark.

When no responses were forthcoming, last night, I followed one of your earlier posts and read up the KB. It seems that currently within CS's hangar, only the 777 is FSX-SE supported. Support for others is due to follow.

But I will, for now, try your suggestions, as the Pax version installed, and flew ok, although I did not check lights or smoke as you had observed in one of your posts.
