Dual monitor 6600GT question

[imported_mson]

I have a dual monitor set up on my 6600GT. I want the primary monitor to be on the right and the secondary monitor on the left. I want to move my windows to the left side of the screen to move them to the secondary monitor, currently I have to move them to the right side. I can't find a setting to switch this. I tried switching the inputs to the video card and that didn't work.
