I dropped back to NBCog dated 12/11/11 and the artifact doesn't show. At the same time, the procedure below works without errors.

I procure the latest CofigurationOfNBOpenGL from:

    location: 'http://www.squeaksource.com/NBOpenGL'
     user: ''

I run the following in a workspace:

ConfigurationOfNBOpenGL project lastVersion load.

NBInstaller install.

Now, when I evaluate:   GLTTRenderingDemo new OpenInWorld.


Pharo hangs. cmd+. doesn't interrupt.


Sigh....
