[Zope] Newbie: trouble getting started under Windows 98

While I expect to eventually be working under Unix (once I can convince my hosting provider to install Zope), at present I'm trying to use Zope under Windows 98. The problem is: it's not working. I'm using the Zope HTTP server, and I can contact the management system just fine, a prowl around looking at everything. But if I try to add an object (whether it be a DTML Document, a Folder, or an "Item" from the sample_product package (which I installed), what happens is: I am allowed to fill out the form where you enter object creation fields (ID, title, etc.), but when I send that form the HTTP server never returns. Any clues as to how to fix this, or debug it, or get any idea as to what is happening? Robert Wentworth
