How to automatically set in Traktor 4 the cue monitor to the deck you just loaded a track in?

Frankiehinrgmc

I was used in Traktor to have the headphone monitor switch to the newly loaded deck.
Something got messed up and I do not have that feature anymore: how could I set it back?

Thank you in advance.

Must be a special mapping. What device do you use to load. Must be something other than a mouse.
