TO CHAS AND 'THE HOLY GRAIL! THANKS

Hi Superfortress,Firstly I think I'm going nut's, I have started speaking to aeroplanes! :-)It's not a tweak, and it's generally not a good idea to try and fix something if it ain't broke. I am not sure if it has any relevance, only time will tell. I suspect someone will regard it as a tweak and try to use it, no one has reported using it to try and fix their working simulation. You really do need to read up on it and understand what it does, you can find the information at microsoft.com.Good luck.Chas
