Probably more Window's related but....

How do I prevent the phantom button that remains on my Start Bar after I exit my OpenGL app? This only happens with several OpenGL apps I’ve made (but not any non-OpenGL) and I am getting annoyed by it.

if your using the old quake gl init stuff this has caused this problem. visit nates homepage it has some source that should init and clear out ok

My experience with this is that I have generated an OpenGL error in my code but the program still runs. Sometimes the errors are subtle cause everything looks OK.
