opengl not clipping/flickering

I am using clip planes, it worked at home but at school…the clipping planes (like glEnable(GL_CLIP_PLANE0) aren’t working right!

It clips the LINES correctly, but the POINTS flicker! HELP!


sorry, I updated the driver and it works but I still have another problem, the specular lighting is screwed up! The rest of the lighting works fine…porting was easier last time

Anything that seems to have any specular component is just turning black. I am using GL_NORMALIZE…anyone?
