None of the default Xenforo smilies work when clicking on the smilie icon in the editor, the available smilies don't even show up. They do show up if you type the shortcode in the message. The smilies are installed and worked fine in the editor before upgrading from 2.0 to 2.1. I even deleted all the smilies and re-imported them using the default smilies zip file posted earlier in this thread.
