Grasshopper while Rihno is Fullscreen

If I try to start Grasshopper while Rhino is in fullscreen mode, there is no GH window. Also If I minimize the Rhino window (here I can see it for a very short time).
I Use the latest release of the WIP Version and OS X 10.11.
regards - Pascal

I use Rhino on a secondary Monitor

We’ve made some major changes to how Grasshopper for Mac behaves with regard to the modeling window (as well as fullscreen behavior) in the next RhinoWIP. Stay tuned…
