Just noticed that if the links on the second layer go past 680px, the final link on the right is no longer shown. I think there is a little more room that can be given to the final link. Just another thought.

Also, on the third layer, it helps to have the links as table-cells so that everything looks decent and the CSS needs to be changed for the width being a mere 150px to being a minimum width of that plus reworking how the layers know when to show in a list rather than looking similar to layer 2. See this.
