When you take a screenshot using SaveBuffer(FrontBuffer()),
the gamma modifications are not saved, the screenshot
gets as in default color,
although when using another program such as FRAP, then
the image is saved perfect, the same as what you see in the screen.

I have also tried with GrabImage() the entire screen and then
save the image, but no luck either ...

One more thing,

FreeImage() does not return an error if
the image handle does not exist :

Graphics 320,240,16,2

img=1234

FreeImage img

FreeImage 4321

FreeImage 0

Print "no error at all"

Not only that but it doesn't even mind if the graphics mode is not set....(using version 1.90)

Yep, that's correct also,
by the way I'm with v1.96

This is normal - gamma doesn't affect a buffer's contents, it affects how it is displayed. FRAPS and savebuffer() deal with the image at two completely different stages on its journey to your display (from two different locations) so they naturally differ.
