While upgrading some plugin, I noticed an error in the Firebug console. It pointed to this line:
function tablistener(){document.getElementById('content').addEventListener('keypress', chooseFunction, true);}
Above this javascript block, I saw this code:
<link rel='stylesheet' id='AtD_style-css' href='http://scribu.net/wp/wp-content/plugins/after-the-deadline/atd.css?ver=1.0' type='text/css' media='screen' />
AtD should only load the CSS and JS on the post & page editing screens, not all over the admin.
