How to disable three finger gestures on touchpad?

view story

http://askubuntu.com – I am using 12.04 on a macbook pro. Everything works really well. I want to disable 3 finger gestures. It is way to easy to accidentally drag/move a window(3 finger gesture) while scrolling(2 finger gesture) when using a touchpad. I found this answer on ask ubuntu. It was marked answered but it is not. The functionality is still there. All this recommendation does is disable the drag marks on the window. This may be tricky because I want to disable 3 finger gestures but not 2 finger gestures. (ie I don't want to disable touchpad gestures all together) (HowTos)
