Strange behaviour in color of the images????

I change the resolution to 640x480 and nothing occur, the same altered image. I don't think that this is video ram problem, because se same image diplay good in B3d.

The PNGs images are saved in 8 bits (256 colors), the PNG image saved as 24 bits in B3d show fine, but in BMax, grrr the same problem.

I upload to site both images, the image called good.jpg is that i show in B3d, and the other "wrong.jpg" in BMax, both images has capture by PRINTSCREEN Key, and then was saved in JPG format.
