I assume you have a mouse with thress buttons and one whell. You should try this:
Section "InputDevice" Driver "mouse" Identifier "Mouse[1]" Option "ButtonNumber" "3" Option "Device" "/dev/mouse" Option "Name" "Autodetection" Option "Protocol" "imps/2" Option "Vendor" "Sysp" Option "ZAxisMapping" "4 5" EndSection
You don't have to emulate a third button if your mouse has one.
Could the following be the problem? No.
