Hello Ian,
Sorry for the delay I have been busy just recently, I seem to have achieved the impossible, ignorance is bliss, thanks for all your help I will do as suggested Ian on one of my PC`s, install the RAF Collection correctly and compare your version of Leuchars with the Alpha- sim Leuchars, I am sure you are correct in your comments about the Scotflight Scenery, I do enjoy the AI`s, in the Alphasim version. I apologise for confusing everyone, my original email was as to the compatibilty of Scotflight with Vista, when all along it was myself causing the problem. Thank you for your time and most of all thank you for your patience, I promise to buck up.
Stan
