when i try to texture map on several different pop-up windows i get the following warning when i try to open the windows: glutSetWindow attempted on bogus window. The window as a result does not open. One window however always seems to open for me but the rest won''t.Could somebody please tell me what im doing wrong!

I am no openGL expert, but please try and explain your problem with a little more detail. The error message you get is not familiar at all, so explain what you are trying to do in more detail, then maybe someone can help you, later-

glutSetWindow only works with window IDs returned from glutCreateWindow, not Windows API window handles.
