Rekordbox video problem & suggestion

hello all.
i'm hoping there is a simple fix to this but i haven't found yet so i'm asking here. when i maximize video screen for videos it blacks out my laptop screen. so i have to drag window to fill screen leaving bar across to tvs in club and it looks kinda bad. does anyone know how to make this not happen?

all is there any possibility that video program can use upfaders only and not have to use crossfader in a future update?  i along with lots of djs i know don't use the crossfader and this is a unneeded step since the upfader is already doing what it needs to do, how hard would it be to click disable crossfader for those of tut that don't use?

thank you
