[Zope] ZClass not displaying in Tree View?

I am experiencing a weird problem. I have a zclass that extends ZObject and ZObject Manager. I have added it to a folder and it will not show up in the left hand folder tree view within the manage interface. I have had the zclass there for months and just noticed that it is not in the folder view. I have other zclasses that extend the same base objects and they work just fine. Any one know what the problem is? Thanks, Chris __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo! Auctions! http://auctions.yahoo.com
