OK... I hope you understand that you are operating so far outside of 
Pipmak's primary scope here that I treat the particular problems you're 
encountering with low priority.

You need to glEnable(GL_DEPTH_TEST), too. But as I mentioned, I suspect 
that having the depth test enabled all the time will mess up (i.e. make 
invisible) a lot of things. glDepthFunc(GL_LEQUAL) may help somewhat in 
that case.
