Don’t use menus like this JS Menu from allwebcodesign.com . If you noticed there is a “?” at the end of the file name. 
This query string is in each menu item.  Guess what, the search engines look at about.htm? and about.htm as two different documents and Google will give them both PR.  What this means is you will have each page voting PR to a non-existent page.  Can you say PR bleed.
