If you look here: http://cmw.net/conferences/radio-interactive-summit/ and focus on the top menu, hover over the word "international" and you will see the drop-down appear. The issue is that the 3rd level drop-down is appearing also (it should only appear when the last item in the 1st sub-menu is rolled over (2013 Focus Spotlights).

I can hide the 3rd level menu by doing this:

ul.dropdown ul li ul li {display:none;}
However, I can't seem to make it re-appear when the 2013 Focus Spotlights menu item is rolled over.

I tried this, but it didn't work:

ul.dropdown ul li ul li:hover {display:block;}
Any assistance would be appreciated.
