Comment 3 for bug 718885

@Panagiotis, the patch looks quite good, thanks a lot for that!

I am afraid it is slightly inconsistent with Unity 2D's behaviour. In Unity 2D the menu is more transient than in Unity 3D. It does not require a click to exit it. It will disappear when the user is not hovering for enough time which probably means that the user went off to doing something else.
