I'm trying to use the GLTools library with glew and wglew to make a OpenGL windows screensaver. Something is going wrong with ShaderManager.InitializeStockShader(). I set up my windows rendering context no problem and specify that I want to use OpenGL 3.1 functionality, but I'm not even sure if I need to use OpenGL 3.1 to accomplish my task. I just bumped it up thinking it might solve my problem. It didn't. Has anybody had problems using the GLTools library with glew or wglew? Because I think that's where the problem lies. If anybody could shed some light on this problem I'd appreciate. If you need more detail on what my issue is or need me to post my code just tell me and I will. I'm just hoping one of you out there knows what I'm coming up against from what I've explained so far. Thanks guys.
