A normal iconified - * window with an icon has an NSView which is the same - * size as the window was when it was iconified. It - * also has its isMiniaturized property set to YES. + * This is a 1-line hack to work around some unintended + * Mac-specific behavior. If a window gets iconified + * or withdrawn too quickly after it is created then it + * will not have a dock icon and it will not appear in + * the Window menu and it will not appear on the + * screen. It cannot really be displayed because the + * bounding rectangle of its contentView will be a 1x1 + * rectangle. But it turns out that it can be made + * into a KeyWindow, and that doing so causes the dead + * window to be deallocated just as if it were a normal + * window. Unfortunately, however, that has the side + * effect of adding the degerate window to the Window + * menu, which is inappropriate since it cannot be + * opened by clicking its Window menu entry.
