================
- Fixed ``AttributeError: portal_windowZ`` in show_window template,
even though this template seems unused. Note that in version 1.3b3
the id ``portal_windowZ` was renamed to ``portal_windowz`, with a
lowercase ``z``. If you get this AttributeError when viewing
windowz (also with other templates than show_window) then you have
probably upgraded from an old version and the tool on your website
still has the old ``portal_windowZ`` id. In that case you should
deactivate the windowZ product in the Add-ons control panel and
activate it again.
