I have a site set up with the WordPress Twenty Ten theme. I edited the CSS in order to make the nav bar elements stretch across the nav, instead of piling up on the left side. Now, however, the top level pages can be clicked on, put the child pages are disabled and disappear upon scrolling over them in IE. Beyond bizarre. Any help would be much appreciated.
