Why is this arm bone bending the other way after exiting edit mode? I have a bone and I'm giving it a slight bend for a pole target, and on the right side of this image



the arm is bent the other way. Its also bending the other way when I move the ik. Help please.
Its standard practice to add a slight bend in the arms when in Edit Mode, which is what Faceb is eluding to.

That said, you can quickly fix your problem by changing your Pole Angle to 180.
