Pen tool behaves differently in CS6 photoshop. Click and drag out handles, click and drag handles for a second point, grab path in the middle and drag at right angles to the path. Instead or the handles getting longer or shorter the direction of the handles changes. This is unlike previous versions of Photoshop and I think it is a bug.
I'm not sure what you are referring to in the tool bar. I want to drag out handles tangent to the shape I'm tracing, then pull the path out so that the handles are the right length to conform to the curve - just like previous versions. Now, when I pull on the path the handles change direction and that screws up the path on the other side of the points. What do I look for in the toolbar?
