Hanging Black screen RoadHog

I have had a couple of hanging issues where there screen goes black, pig+open+
This gets a bit nervous, I thougt I upgrade to 2.3.0 and it still crashes.
I'm not really shure why, sometimes when I'm running a show and are tapping, another time when fixture shedule and fixture edit was open at the same time and I pressed OK in the fixture shedule it went blank.

Is there unresolved hanging issues or did I get a bad console?
