Track IR wont solve the multiple monitor situation - It does work but only useful in 3D pit mode.
For multiple monitors you probably need something like a Matrox Triplehead.
I assume you are just extending the desktop in windows - I dont think that will work.
Sorry, I should have given more info. I have 2 monitors with a Radeon card with a DVI output and an analog output. I would like to have Falcon running on one monitor and my desktop on the other with the desktop extended. If I have "duplicate" set in Display settings Falcon of course is on 2 monitors but there is no way to get back to the desktop except to exit Falcon, which is tedious. If I have "extend" set in Display settings I can have Falcon on one monitor but it is on the wrong one. Then I have to reconfigure my displays all over again when I exit Falcon and go to FSX.
