--- Comment #3 from Nikolay Sivov bunglehead@gmail.com --- Turns out it's a feature of comctl32 v6 buttons. It continues to draw bitmaps even after original object was deleted. Class button control from user32 behaves like wine currently does - it fails to draw. However BM_GETIMAGE return value is consistent and is always the original handle.
