Any idea why sometimes the drop-down menu disappears when I move the mouse from the About to the drop-down menu?
Thank you, Asaf

Did you fix it? Or on which browser? On Chrome and Safari it works for me.

The problem occur when the mouse move slowly down from the About title to the menu. Tried to make this space smller but I still get it.
