[HOpenGL] Texture problem

I would like to write a program that does the following: 1. Create a TextureName for later use 2. Initialize GLUT and GL routines, creating a window 3. Draw something using the TextureName of step 1 Unfortunately, creating the TextureName seems not to work if no window was created. The program above will draw an empty polygon where it should have drawn a texture filled polygon. If I change step 1 by 2 (and vice-versa) the program works well, but this is not exactly what I want. Does anyone know why this happen? (in other words, why must a window be opened BEFORE I start do deal with a TextureName?) -- Andre
