If anyone is suffering the the dual monitor problem in Vista with FSX, where the freeflight settings for example show on both but then go just black and/or black and white flashing then there is hope...... It looks like a simple screen resolution problem between Vista and NVidia, since at least on my setup the resolutions offered are different. Even selecting 1024 X 768 doesn`t fix it, seems a mishmash somewhere! Nor do any of the present updated drivers help, fear not though, took a while but heres a simple fix for now that appears to work.
(1) Start FSX
(2) Freeflight and set up as you wish, daylight puhleese! We need to see if its fixed......
(3) Press `
Alt + Enter` to go into windowed mode
(4) I know its working, please don`t play yet......
(5)
Maximise the window(6) Press `
Alt + Enter` to go into full screen mode
(7) Now drag your caboodle to the other monitor
(8) Did you see (1)

Go play, after sending the kids out, kicking out the dog and then realising you have neither!!! ;D
