It's just a warning, but i wonder why it even pops up ? According to teh Documentation, size_t is unsigned int. So why does my compiler warn me every time want them implicitly casted ? They are the same, or aren't they ?

There is an unsightly black flicker around the edges of the bitmap, they are only there when the window is being moved, almost as if the image is being drawn to the wrong place.
