I created a sitewide navigation that uses wp_list_pages.  And with CSS have a nice horizontal drop down menu. This was working great until I installed Scoper, and now that same exact line of code returns about 50 pages instead of the ones that have a metavalue=homenav.  I have tried a few different ways but always I get many pages returned.

<?php $newNav = wp_list_pages('title_li=&sort_column=menu_order&depth=2&metavalue=homenav&echo=0');?>

Please let me know what I can do in order to keep my menu and use Role Scoper.
