OPENGL problem in WIN NT 4.0 is solved ?

And just question .

How used 'hard ware OPENGL video bord' in LW intel?



1. OpenGL NT 3.51 app won't work under NT 4.0

I have an OpenGL application which worked under NT 3.51, but won't under
NT 4.0.  One problem is that if I suspend the context using
wglMakeCurrent (NULL, NULL), and then assign it again using
wglMakeCurrent, I get an illegal memory access in __glInitDepth16 for
using a 0 pointer, with the following stack.

CRotateXlate::do_xforms() line 1614

Another problem is that after drawing an object around 100 times, it
draws very slowly.  I haven't had time to look into this one.  I assume
that these problems are some quirk with NT 4.0, or with OpenGL for NT
4.0.  Has anyone had similar problems and knows the solution?
