title: Drupal 7 Admin Overlay positioned to high
body: <p>This is a problem that seems to have occurred for no reason. Everything was working fine, and now all of a sudden the overlay iframe for the admin interface renders too high so that any tabs are rendered underneath the toolbar. I hadn't edited any css or html so I don't see how I could have done this. Has anyone seen this happen, and how did they fix it? I'm attaching two images. One shows the site as it is (incorrectly). The other shows another similar site that is functioning correctly. Also, notice on the incorrect display, somehow the toolbar is showing OVER the browser scrollbar.</p>
