MozBlog borken on Mozilla 1.3b?

I've tried to get MozBlog working on a couple of machines, both running
1.3b.  On one I installed 6.14, then 6.12  Both times when I try to
configure a new server, it just sits at 'Checing Settings' and does nothing.
 Ethereal shows NO packets being sent so its not even trying to contact the
server.

Then on another machine with a fresh install of 1.3b and MozBlog 6.12, it
does the same thing.  Has anyone else seen this?

I tried to figure out what a prefs.js section would look like for an 'other'
type blog server from the MozBlog code, but wasn't sure how it IDed the
servers (can you tell I really wanted to get this working? :) )  I was going
to try and specify all the parms manually.   LOL
