Using the Snapshot I get the following when doing an F6:

Error: Missing GL version

Trying to get the info from Help>Library Information I get the following: 

A critical Error was caught. The application may have become unstable:

When I try the basic shapes I get this:

cube(20); 
sphere(20); 

Console after F5:
