Ok, here's what happened -- in trying to figure out how to make Radio post to MovableType I had misconfigured the blogger bridge preferences and then attempted to post an article. I then fixed the prefs, posted another article and it tried to update the prior posting and generated an error. It kept doing this, even though it did not show me that initial post. I found it in the "ManilaBloggerBridgeData.root" file and removed it. I think it should now work properly.
