.av_secondary_right .sub_menu>ul>li:last-child, .av_secondary_right .sub_menu>div>ul>li:last-child{ border:none; margin-right: 0px; padding:0;} (line 108 in layout.css)
That last item on the secondary navigation in the upper right needs 10px on padding left. Without padding, there is no space between the dividing line and that last item.
The same is probably true for the navigation in the upper left (line 107)
Thanks!
