slight shadowed double vision of icons

Hello everyone,

I recently installed a radeon x1800gto and am using it on an HPL1940
LCD. The problem I’m having is that the icons on the desktop (XP) have
this slight double vision that offsets to the left. The strange part is that
this effect is no visible on the wallpaper, or when gaming, although it
does occur when online, or when running any standard programs. I
have to admit it’s driving me insane since the effect is causing me
massive headaches. Can anyone PLEASE help me?
