Office 2007 and dual monitor card issues

I have office 2007 installed with a radeon x1300 series dual monitor card. I have lost the capability to change the color scheme from blue. Office worked fine when 1st installed with a ATI dual monitor card but then all of a sudden, it changed the color scheme to blue. I have reinstalled the drivers including latest 1’s, unistalled office and reinstalled without any effect.I have even tried a different dual video card (radeon)and have the same result. When I remove the dual monitor card, the color scheme works on the single monitor. Any idea’s?
Thanks ,
Mike
