Personally I hope that Flight is the equivalent to Windows 7 like FSX is equivalent to vista for me at least.If Flight was built from the ground up that would be even better, I'm sure you've all seen how many FS.exe's from past versions are in the main FS folder. I'm guessing that if you dug hard enough you would find some of Bruce Artwicks ASM code from the late 70's / early 80's in there. All that bloating code is bound to cause issues.James
