I'm tryng to use Webfolder with Casey Duncan Document Library with my Zope 2.5 on Win2Kpro, this is my experience, but my Zope lebvel is near to zero. I can create a webfolder to http://myZope:xxxx/DL/Documents where xxxx is my zope webdav port and DL my Doc Library instance. I also can modify a document but only one time, at the second modification I obtain a "read-only document" message. Ciao, Michele
