OK, I discover why it didn't work on my graphics card! In fact, some times ago I decided to put a depth of 24 on my windows desktop (in "display properties"). And since then, it was indeed impossible to have 3D in windowed mode!!
I put the depth of windows back to 16, and now your program is working fine!!
And it looks very good, even if I didn't understand all the options (texture guide, clone brushes, ...)
