"No, really, I DO know it all!" <-- Yeah, Right!!
I wanted to suggest three things. First off, are you sure you set the shade model to smooth or gourad? If it''s set to flat (default) then the anomaly you''re experiencing is supposed to happen. Second, you should try winding techniques. By default, the front of a polygon is facing you (or out) if you set the vertices in a counter-clockwise motion. If you made them all in a clockwise motion, you can change that by setting the gl command for culling to GL_CW instead of GL_CCW (default for counter-clockwise). And Last, you should calculate normals for your ploygons, that is how to make sure OpenGL nkows how to handle lighting from the 90 degree angle of the polygon face.
