Hi All, I have discovered that the following bit of code works in Opera, Konqueror and IE but not in Mozilla. Does anyone have any ideas? <form action="/mysite/acl_users/logout" method="post"> <td class="ToolBar_login" align="center"> <input type="submit" value="Log out" size="5"> </td> </form> I am running: (Zope and Python compiled from source) Zope Version (Zope 2.6.0 (source release, python 2.1, linux2), python 2.1.3, linux2) Python Version 2.1.3 (#1, Jan 31 2003, 14:51:52) [GCC 2.95.3 20010315 (SuSE)] System Platform linux2 Thanks, Mike
