Hi, To put you in the picture I've had several issues migrating over to win7 64bit ultimate (in some respects I'm sorry I did) but anyway I think I have just about ironed out most bugs/glitches but I have one that's really annoying me, I cant save a basic fsx config. example I have ultra high detail on most things but pmdg 737 hangs when I select this so I have to manually alter aircraft graphics to high which works ok but if I save it and close fsx and load it up again it's as if it didn't save it, no matter what changes I make in my config it doesn't appear to save them.??? Any ideas would be much appreaciated as I'm now losing the plot after everthing else that's happened trying to upgrade to a 64bit system that should be apparently better. Thanks
