Hi, first of all, great theme! I love it and it's amazing.
Just one thing I've noticed though, there seems to be a bug (I've updated to the latest version, so it's still present) in the navigation menu when there are more than two sub menus. The image will probably do a better job in explaining what I mean:
Basically, when I'm hovering over "Event Photographs", it's child menu appears which as it should, but the grandchildren menus also appear at the same time and overlap each other. In this instance, the children of "2010 Event Photos" and "Events Prior to 2010 Calendar" both have children and both are simultaneously being displayed. Could you possibly update the theme to fix this?
