Hello, i've what i think is a rendering problem checked on Zope 2.8.5 and Zope 2.9 (tried on unix and windows os): download from microsoft website the sdk for Windows Media Center (http://www.microsoft.com/windowsxp/mediacenter/developer/default.mspx). Inside there is a folder called HTML Templates. There you can find some html pages designed to be seen on media center. You can normally view them using IE. Now transfer the entire directory inside Zope; if you open the default.htm files the highlight of buttons and objects is not anymore working. IE doesn't complain about any errors, it just don't work. I've tried uploading the same directory to Apache and pages are working. These files are full of javascript but i really can't understand what's happening. Thanks, Bruno
