I have a PopUpButton that launches a Menu. In addition I have
a ToggleButtonBar control. If I expand the PopupButton menu and
then go to click a ToggleButtonBar button the menu begins to
collapse but will leave some portion of the menu as a visible
artifact. Is this a known bug? I suppose one solution might be to
try and remove the animation for when the menu closes and have it
close immediately. I'm not sure how to do that however and would
prefer a solution where the menu can maintain it's close effect.
