TheV that the arrow actually rests on will jump forward in the direction of the target about 1/16 inch when I have it thumbed in the up position then go to manually pull on the cord to let it down. It is at that very moment that I pull on the cord that the click and jumping occurs. Actualy, the clicking is really not a solid click, it's half way between a click and a creek. It's almost as if there is some play in the mechanism somewhere and pulling the cord releases the spring loaded rest which then takes up that little bit of play.

thanks guys.
