Yes. I am facing the same problem. I am updating the menu in performSelectorOnMainThread. If the menu is kept open without any event then there is menu refreshing issue ie. sometimes some items will be shown twice. When I move the mouse over items then it will update. But, when the menu is open and mouse is still then the menu won't update. Is there a way to update the menu while it's open without any mouse movement like System WiFi menu?
