--- Comment #6 from Fabian Maurer dark.shadow4@web.de --- Actually, this is two problems:
1) Since BCM_SETIMAGELIST is implemented, this is used instead of BM_SETIMAGE. Since the imagelist is never drawn, this won't render.
2) Since a refactoring, the button won't be drawn if an image is set but the text is null.
