Grasshopper begining video (RH 6) has different results than my RH 7

So I’m doing Grasshopper tutorials. The videos are using RH 6, I’m using RH 7. I’m at the simple process of placing a single point with X,Y,Z sliders. In the video, when he moves the sliders, the point (X) in the Rhino screen moves as do the coordinates in the Grasshopper panel. In my RH 7, the coordinates move but nothing happens in Rhino. Obviously something needs to be switched on somewhere? Now I’m at a standstill on lesson 1.

I shut down rhino and restarted and now it works.
