3 monitors and XP

Hi,I have one computer here with:GF2mx400 32mb AGPTNT2 32mb PCITNT2 32mb PCIso 3 monitors in winXPThey work fine, I'm trying to test magenta on this computer in a network with FS2002, my problem is that magenta is only updated in AGP display, if I drag the window to one of the PCI displays the screen isn't updated...I tried many detonator drivers no sucess....any settings ?Maybe it's an open-gl thing...but I can't manage to get all the 3 monitors updating magenta or other application... Thanks,Ulisses
