hii just upgraded my video card to ati 9800pro and performed a clean install of winXP and fs2004 and pmdg737ngthe system that i am running is P4 2.61G ram 3200ati 9800 prowith dual monitors 19in lcd and 17in lcd secondary (from same card)this is what i am experiencingwhen i run fs2004 then load PMDG then choose 700 model and then airport the plane appears on the runway no problemthen i try to open a new view and unlock it to create a movable window then drag this new window to the second monitor and the fs2004 main window goes black/dark and the fs2004 program locks up.now if i do this with a cessna airplane and open a second window then move it to second monitor everything works fine. while in this mode i then choose a different airplane like PMDG 737 and load it and both windows remain visible and fine(prior to this new upgrade and configuration i was running the same system but with 2 video cards an agp ati 9000 pro and pci 9000 pro - and i was able to load pmdg 737 and create multiple windows on both monitors without any problems)any suggestions would be greatly appreciatedBo

anyone with any ideas why this is occuringBo

Hi,I don't know directly what's the origin of your problem, but do you have the last drivers for the Radeon 9800?What I do know is that the old Radeon 9800 drivers give problems with FS9.So, install the new catalyst driver from ATI and also don't forget to install the DirectX9b(new b-version)from Microsoft.Hope that helpsCheersRobert
