Strange behaviour in color of the images????

Im goin crazy.

I create an image 800x600 in photoshop, when i export
this image in PNG format, the image on the screen
program in BMax change the colors. I mean the image is
blue tones when I see it in photoshop and ACDsee and
on BMax the images look like green tones.

I used 1.10 version, on a Pentium 3, 800mhz, 4mb of
Video, Windows 2000, directx 9. Mi desktop screen
depth is 16 bits.

The PNG image was created by two ways SAVES AS, and
SAVES FOR WEB, and the same problema apear.

Making other test, I save the image in BMP format 16
and 32 bits and the image is not visualize. In 24 bits
option the image apear but with the green tones.

Then when I try with PCX format, appear an error:
"Unhandle Exceptio: Attemp to access field or method
of Null object".

I post this Topic because the images work fine in
Blitz3d.

Here the code source un Blitz3d:

Graphics 800,600,16
SetBuffer BackBuffer()
a = LoadImage("images/background.bmp")

Repeat
DrawImage a, 0, 0
Flip
Until KeyHit(1)
End


Here the code in BMax:
Graphics 800,600,16
a = LoadImage("images/background.bmp")

Repeat
DrawImage a, 0, 0
Flip
Until (KeyHit(KEY_ESCAPE))
End



P.D. Sorry about mi english.
