FS9 and Vista 32 DX10

I had my dedicated FS raptor go bad on me abou a week ago so I decided to add 2gig more RAM and add Vista 32 HE on my system. NewZEgg had a kickass deal so I installed as normal and FS9.1 statrs with the forward view with just the bottom half of the cessna panel .To fix the view to normal I must change a view and then go back.I am running latest Nvidia driver I think 174.25 w/o n-hancer on a 8800 GT 512.Before I goto deep into into the install with all my addons I want to know if this is a DX10 issue with FS9 using a DX10 compatible crad or I am missing some tweak in Vista.ThanksAndy
