I’m a daily Rhino user and there seems to be a problem with my Installation of Rhino 5 64bit. since today i have always a bluegrey gradient as default background. And i can’t change it to my colour or default colour.
Any help would be great.
regards, Jochen
Run the GradientView command.
It’s a toggle.
Thx, that was it. But i’m sure it wasn’t accidentialy commanded. It was after a restart from Rhino.
And many thanx for the quick reply! It was a bad memory about times when i was using solidworks 
If i had used the help, it is very easy to find. 
thx anyway.
