Okay, I don't think we need anymore "Hey, I have this problem too!" posts. This bug has been fixed. You need to upgrade your Xorg Server and associated files. At least that's what I did with my Fedora 10 system. Bug is gone, working perfectly with two Nvidia dual-head cards with 180.22 drivers and four monitors in Xinerama. Thank you to all who have contributed.
