As title, increased the duilib menu, the menu display, if the mouse didn't go to menu, click other places, the menu will not close;
But after the menu display, the mouse through the menu (no other operations), click elsewhere, menu close;
Menu is closed CMenuWnd receives the WM_LBUTTONDOWN message, if the operator is not itself, is closing the menu;
The above issue tracking and found that if the mouse over the menu, will receive the WM_LBUTTONDOWN message, otherwise there won't be WM_LBUTTONDOWN message, really don't know the reason, masters teach you;
