Another piece of info that makes me look - shocked:
- I loaded the cl-opengl OpenGL bindings from common-lisp.net once
again. 2. I just started my lisp process and loaded the cl-opengl package via ASDF 3. A simple (gl:get-error) results in exactly the same error - but no other package is loaded, so I am assuming cl-opengl is not the root cause of this.
I think the problem is that OpenGL on the Mac must be connected to a rendering engine in the thread where you call it. I get crashes with the LispWorks OpenGL code too unless I call glGetString from the event loop thread after starting the OpenGL demo.

Yes, thanks Martin, I know that this is a requirement on OS X. There is just one thread running...
Cheers Frank
