[Zope] Newbie ZClass question

I'm running Zope 2.1.6 on Linux. I'm playing with both IE and Netscape, latest versions. I've just created my first Product/ZClass, Widget. When adding the ZClass I used CatalogAware and ObjectManager as base classes and had Zope create the constructor objects. I can now Add a Widget to a folder. Very cool. Here's my problem: I have now edited the Widget_addForm method and pressed the change button but I do not see the changes when I attempt to Add a new Widget to a folder. I have gone back to the method text and the changes I made are still there. I have turned off all caching in my browsers and hit the refresh button on every page I can think of. Here's my question: How dumb am I? Help! Scott B. Burchill \:)> /:(>
