Roug Installing your Simple Directory of URLs gives me this message when I start up Zope on window98. "that is not valid. This should never happen. (Waaa)." There is something wrong with the permissions I guess but I can't see the error message it generates because either I'm stupid or MS DOS PROMPT is to short on lines. If it was Linux I could at least have scrolled upwards to see the whole error message. I can see that the error must occur in PermissionMapping.py I run Zope 2.2.1b1 on Windows98. The tgz file I downloaded contained three files. __init__.py, version.txt and product.dat. Is that correct? The problem is, that I can't see or Add the Simple URL object from my Add dropdown list. Why is that? I have so far never had any problems with this setup. (I think) It is a development server, so I can knock it off and start again if I have to. I have followed the Installation instructions, and I have successfully installed your product previously on Zope 2.1.6 Cheers, Peter
