The menu worked great until I added a custom image. With the custom header created and uploaded, and the display text set to NO, the menu moves from in between the banner and the post box to on top of the menu.
It seems that removing the Display Text throws off the pagination.
Here's two screenshots that illustrate the issue:
With Display text: http://screencast.com/t/qTpubcyS
Without Display Text: http://screencast.com/t/apQlBYXCF
This happens in Firefox 12 (Win and Mac)
In IE 9 I can't see the menu at all.
In Safari it seems to display fine on both Platforms.
It's up at http://policy.commons.hwdsb.on.ca if you think it might be something specific to my install.
