I've read a bit more on the Next Step windowing system (a bit more). AAAhhhh if I only had the time. You may be on the right track, which still points to the fact that you are deriving the object from NSView instead of NSOpenGLView. NSOpenGLView implements a lot mechanism that are required for Composer (part of the windowing system) to set it up correctly. It may be that in your imp the required initialization procedures are not being done, or the methods necessary to control the actual GL window itself are not there. NSOpenGLView IS a NSView with addition initialization and implementation routines necessary for the GL window.
