// workaround for bug #1397031
//
// windows 95 doesn't erase the background of the state image
// before it draws a new one. because of this parts of the old
// state image will show where the new state image is masked.
//
// to solve this, the following line forces the background to
// be erased. sadly, this redraws the entire control. it might
// be a good idea to figure out where the state images are and
// redraw only those.
