Tsk, sorry Evil SOB but its none of those things:

1) i changed "texture" handle to MYBMP

2) the posx/posy variables are stopped before the dimensions of the bitmap are reached. (Image size 78x33)

3) the image is in 16 million colours!

I also tried the bmp_lock function to, but it seemed to do nothing, and i still get the error!
