    1) Black&white mode means to show the mask that decides what goes into the foreground and what goes into the background. Since page 4 is a pure wavelet image (no foreground), this does not mean anything, and the viewer reverts to the color mode.

    2) Regarding colors, the latest git version displays the backgroiund color of the first page displayed in the image panel. This is what is intended. The released version only honors these annotation when showing single pages.

    Regarding djview - better make option to override user setting and specify backcolor mandatory
    Linux is nothing to me - too complicate system
    When will be win 32 version ready (i had a task to make screenshot of djview for english users and i cant do it because of no interface language change to english)

    Regarding backcolor - sometimes i use different backcolor for cover and now i find, that only caminova plugin support it quite right. So if user open my ebook by third-party viewer - he see nothing of my designer efforts. It make me sad. I like PDF properties, which can adjust initial viewcarefully and supported well by third-party viewers.
    For djvu wierd freedom - for why?

    djview has no way to simultaneously show pages with different resolutions of display modes. This is not going to happen. The background color is not the one associated with the first page shown in the screen. This is all I can do at this point.
