OK,
My message talks about a genuine windowless graphical full-screen mode. Now I see that what you actually have here is in fact a fixed-size window.
So it was just a misunderstanding based on improper terminology. A fixed-size window is not a graphical full screen.
Thanks for the feedback though. I think now that I have your assurances, I can try your code on my monitors. Otherwise, I couldn't and wouldn't.
[UPD] I'm sorry to say it but your bitmap scripts crash for me. The offending function is peek(). I'm using the latest build of O2 dated August 7.
