[Zope] Problems with ZClasses...

Okay, I'm trying to grok zclasses. Admitably, my Zope Zen quotient is very low right now, but I'm trying. My problem is, I create a ZClass, and I try to pop an index_html into the ZClass. I can view it from the products screen, but when I create an instance of it and try to access it, it prompts me for a username and password, but I haven't even defined any security on the file. This is in the same folder that I can access other items just fine. What am I missing? -- Man is the only animal that can remain on friendly terms with the victims he intends to eat until he eats them. -- Samuel Butler (1835-1902)
