If you look at my attached Xorg.conf my setup is
Section "ServerLayout" Identifier "Default Layout" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" Screen 2 "Screen2" RightOf "Screen1" Screen 3 "Screen3" RightOf "Screen2" Option "Clone" "off" EndSection
with Xinerama set elsewhere and that still has the problem. All in order, all RightOf so that workaround won't work for everyone. Wish I knew why though.
