Use performSelector:withObject:afterDelay:0 to push your response to the end of the run loop, giving the UI a chance to update first. It's what I do when a button (etc) is going to trigger something that won't be instantaneous, where the button shouldn't keep showing in the pressed state while it happens.

When I get a mouseUp in my view, I need to flash the hilite (I'm guessing just draw it a couple times with a short delay between draws), dismiss the menu and perform the action associated with the item. These seem like the right methods to use, but the menu is not closing before the action executes. What's a better way to do this? The MenuItemView sample app also has this problem when you click the Button.
