Why can't I turn off my right click? I'm running 10.10, and have a wireless mighty mouse. I want to turn off the right click on the mouse. I went to System Settings > Mouse, and set the "Right Click" function to "Primary Button" instead of Secondary. However, this has no effect, and the right click still functions as a right click. Why is this?
For my Magic Mouse, Setting the Secondary click option to "click on left side," simply makes it so that the "right click" (contextual) behavior is reversed.  i.e. left-clicking brings up a menu, and right-clicking is a normal click.  UNchecking the checkbox beside Secondary Click turns off the "right click" behavior altogether.
