a bit of hero window

help needed - make something to prevent changing surface stored in CHeroWindow::background. I do not overwrite it, but it changes dramatically with every call of CHeroWindow method!

And besides - is there anything to make my window displayed easily, without calling show() every frame when it should be displayed? any machanism?
