I have two sidebars configured in Newscast but the far right sidebar is being moved down to the end of some of the posts. On my Mac with Firefox 14.0.1 it only happens on a few posts, but other people have told me it's happening on the whole site for them, including the home page. Here's a post where the problem shows up on my browser : http://www.feasta.org/2011/11/15/in-memorium-richard-douthwaite/ .
Any idea what could be wrong? Thanks for your attention.
