In the navigation area in the upper right corner AND in the main navigation area below and to the left, the vbmenu script appears to double.
The first is the QUICK LINKS area (see the down arrow to the right of it?) and the 2nd is to the right of the SEARCH button.
I noticed this after upgrading to vb 3.5.4. Why is it doing this and how do I fix it?
