This is happening because you are doubleclicking the .3dm file in order to start Rhino, and the relevant triggers are not being fired to catch the loading of the plugin data. Instead, start Rhino, then File->Open the .3dm file. I have pushed this issue to McNeel to see if there is a way around it.please, take a look at this short video I made. The bug of "camera visibility" doesn't seem to be resolved. As you can see if I re-load the file while rhino is running, everything works. But If I close rhino and re-open the file the bug is still there.
