@PT, I think that solution is going to be dog-slow. It really should work by writing to the backbuffer and using flip. Do the example programs work for you? What version of BB are you using? Are you running windowed or fullscreen? If the example programs work on your machine, I would start from there. If not, then you need to check your graphic drivers or test it on another machine. Something's not right.
Good luck,
