In the Sleeping Dogs, there is a mission I'm supposed to drive a blond asian girl "Amanda" to some Kungfu school. I took her there and then the Kungfu master is now testing how 'trained' I'm. so, I'm suppose to do a "sweeping knee kick" or something, the screen instruction says "Left Mouse button, Left Mouse Button, Hold" But whenever I do that, my character randomly kicks and punches. So the mission is not progressing. The dummy opponent is not dying either. I've spent like 20 minutes doing that damn thing so please tell me how to pass this mission? What is the correct key combo for PC game? thanks.
