Thanks a lot for that, longbreak754 and to all who have given hints.
I shall go through longbreak's list during the weekend when I can concentrate !
So far and following the other hints, I'm still at stage 1.
But the above with longbreak 754's possible solution looks very interesting.
Oh yes, I noticed I have config files from FSXse also with the FSX config. I renamed that one as well.
I do use FlyInside, a VR hook for my CV1 goggles.
I know that Flyinside also has config files. Not sure to rename those.
But The FSX program I don't think even gets that far. All stops in less than two seconds.
Might first wait until after this weekend?
Great support of which I do appreciate.
Cheers.
