Sketcher/ CREO9 / Dimensions whitness line selection priority

Hi all 🙂 

in C9, compared to c4 that I'm used to, dimension witness line has selection priority over everything else.
I.E: 

auto - added angular dimension is exactly where the sketched line ends, and when trying to select line endpoint, I have to be aware of not selecting the dimension, if i need to drag the geometry. Else, when I try to drag geometry, but with this blue dot selected it drags the dimension and locks it as user modified.

This is more than disturbing, as the dimensions at random have this "blue dot" drag point exactly where geometry ends, and i did not found a use case for selecting such witness line instead of dragging the dimension text/ value itself.

question is, does config option to erase these dots exist? or to change this priority back to geometry ? so I don't have to mess with selection of the witness lines instead geometry?

Thanks, cheers 🙂
