Concerning the PTK install problems. I'm writing to tell you that for me (and I guess for everybody else) everything works fine after upgrading "Methods.py" in ZClasses as an earlier posting suggests. (Don't find it right now) I guess that upgrading to Zope 2.1.3 works, too. Didn't check. The CVS can very easily be accessed over the web: http://cvs.zope.org/cgi-bin/cvsweb.cgi/ Joachim.
