Minor bug: If you mouse over a menu option as it's fading out, you can open the sub menu for that option and still have the primary menu dissapear. So you end up with the parent menu gone, the sub menu visible, and the "mouse over" style applied to the now invisible option.

fade out bug
Just for your info, it has to do with internet explorer's filters and transitions applied to the menu. If you are using them you might set the fade out to happen faster which may keep that from happening. I saw what you meant on the milonic site. It will only happen in internet explorer since those effects aren't read by other browsers.
