Steve, I don't know what the problem is, but I have a temporary fix. The problem is something to do with providing a "help" button. In lib/python/App/manage_tabs.dtml, at around line 148, comment out this entire dtml-with block: <dtml-with "_(option=manage_options[a_])"> <dtml-if "option.has_key('help')"> <td align="right" valign="top"> <dtml-var "HelpSys.button(HelpSys, REQUEST, product=option['help'][0], topic=option['help'][1])"> </td> </dtml-if></dtml-with> -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net
