[SDL] SDL + OpenGL problem

[Thiago Silva Conceição]

I have been following OpenGL NeHe's tutorial and written some mutated 
versions of the examples codes available there. The problem is that 
sometimes when I run the program it looks all messed up, static, not 
even hitting the keyboard seems to move a thing (the keyboard works, 
toggling fullscreen works), and then running the same program without 
any modification nor new compilation it runs fine.

I think the code is OK, besides it'd be to big to paste it here and no 
one would read it.

I'm using a GeForce 2 MX with Nvidia drivers and gl implementation on 
WindowMaker 0.80, X 4.1.

Any idea of what could it be?
