Thanks for the info. I will try it. The setup with Medallion is without internet access though, so it all has to be in the computer. I am trying to make a 4 screen display operate and MSFS is the only one that can do that with one computer. X Plane is used on the new PA18 sim but it has three computers to run the three screens. X Plane has weather that can be set on the fly. But I am stuck with MSFSX.
Is there a forum where the this stuff is discussed? Most school kids know more about it than I could ever hope to learn and maybe they have a place on line where they talk about it?
