	// It is safer/easier to destroy the GUI windows prior to the menus (especially the menu bars).
	// This is because one GUI window might get destroyed and take with it a menu bar that is still
	// in use by an existing GUI window.  GuiType::Destroy() adheres to this philosophy by detaching
	// its menu bar prior to destroying its window:
	for (i = 0; i < MAX_GUI_WINDOWS; ++i)
		GuiType::Destroy(i); // Static method to avoid problems with object destroying itself.
	for (i = 0; i < GuiType::sFontCount; ++i) // Now that GUI windows are gone, delete all GUI fonts.
		if (GuiType::sFont[i].hfont)
			DeleteObject(GuiType::sFont[i].hfont);
	// The above might attempt to delete an HFONT from GetStockObject(DEFAULT_GUI_FONT), etc.
	// But that should be harmless:
	// MSDN: "It is not necessary (but it is not harmful) to delete stock objects by calling DeleteObject."

	// Since they're not associated with a window, we must free the resources for all popup menus.
	// Update: Even if a menu is being used as a GUI window's menu bar, see note above for why menu
	// destruction is done AFTER the GUI windows are destroyed:
	UserMenu *menu_to_delete;
	for (UserMenu *m = mFirstMenu; m;)
	{
		menu_to_delete = m;
