Its working, I had to fiddle with the button mapping sequence. I swapped
2 & 4, added your .xbindkeysrc, ended up with 1 8 3 4 5 6 7 2, I wanted
my middle button on 4 and I get a fourth button I had not used.

According to xinput:
Buttons supported: 8
Button labels: "Button Left" "Button Middle" "Button Right" "Button
Wheel Up" "Button Wheel Down" "Button Horiz Wheel Left" "Button Horiz
Wheel Right" "Button Side"
