normals question, I think

When I push the draw normals button in edit mode I get blue lines coming off the model. When I push it again it should go off but I have LESS blue lines, instead of being in the center of my quad they are at the corner, so each quad has 4. Is this a bug or have have accidentally pushed another button?


You turned on Draw VNormals (just to the right of Draw Normals). Vertices have normal vectors too.
