I've got it installed and it works like a dream with one small quirk.  Whenever I perform a form action, I get this in firefox:
<my_site_url>http could not be found.  Please check the name and try again.
In IE, it's a "page cannot be displayed" error.
When I refresh, whatever form action I was trying has been carried out successfully.
Any help is appreciated.

I'd bet it's got something to do with your webpath config variable. It's probably set to "http://...something..." when it should be "/zenphoto" or similar.
