Hallo! - I tried to compile the source and all was OK! - Then I converted the source to a class and all was OK! - As I used the Class with other souce of me... it wasn''t OK! I see the problem is, if I enable GL_TEXTURE in InitGL() it doesn''t run. If I disable GL_TEXTURE in InitGL() it doesn''t run. But, if I write nothing... all is OK!! Why can''t I enable or disable GL_TEXTURE? I hope you know what I mean. Cheers Your Kidney Stone

source of which lesson?
