Resize didn't work with bezier handles correctly. That is because bezier has preleminary work for Individual Center in edit mode.

While I was there, I cleaned up individual center a bit, it was messing with helpline.

For fun, set the center mode to Individual Center, create a bezier circle, change handle to free (H) and Resize or Rotate. Fun isn't it! :)
