It worked until I attempted to install a python script that I had downloaded as a "Word" file and copied into the editor.
Now it will not display the "System" in the "User Preference"
In the menu for choosing the materials there is nothing. Not even for choosing the material type or color, and there is no preview.
I had to go into the "Node Editor" to choose the "Shader" and then the shader showed in the "Materials"
I tried resetting the settings for the graphics board.
