Facebook like dialog hidden behind other page elements
===

I am having trouble getting the facebook pop out dialog to be on top of my nav bar and slideshow here:
http://d14599.u62.c14.ixinstant.com

I have search for several hours and all the solutions have not seemed to work.  Here is a list of what I have checked:
-overflow:hidden on other page elements causes problems.  I looked into this but my nav bar does not have this property.
-z- index only works for positioned elements.  I made sure my elements were positioned relative or absolute.
-I tried directly styling the js created facebook elements using things like
      
       .fb_iframe_widget{
       display:block !important;
       z-index:9999 !important;
      }

I'm not that good with CSS but have never been stuck this long on one single issue.  

I am assuming the issue actually is with something I have done wrong elsewhere on the page, like the navbar itself, but I cannot see what it is.  Any thoughts would be greatly appreciated.
