NOT moving with mouse

i've disabled mouse walking and i can still click and make me move to that direction (i HATE that) if i ever misclick a guy ( click beside him instead of on him) it moves me over there. How can i disable that? i thought it possibly was maybe a move forwar dbutton, but ive chacked all of that. so there anyway to do this? thanks for reading.

If you go into the options there should be a radio button that disables movement by mouse, I am not 100% sure where it is, as I am not able to get on right now.
