A FillRect() bug?

Hi,
I just noticed something weird. The minimal sample debug windowed version fills the screen with RGB(128,128,128) and write some text. It works as it should.
However the release version in full-screen does not fill the screen with grey. It stays black. The text is properly written, but no grey background.
I tried both the compiled version in the gapidraw distribution file and to recompile the source, no change.
I then tried the MFC demo and here is the screen that I got from the release version:
This is again the exec from the GD201d release.
Is it possible that there's a problem with FillRect()? I just checked but it doesn't return any error code.
