Hi Don,
I think there is an issue with this fix. When I edited one of my existing posts, in which there was no Body. The update apparently went OK, but nothing appeared on my site. I went to edit it on the site, to see if there was something left in the Summary overriding display of the Body, (which is how my blog is set up to display - display Detail:400 if no Summary), and there was nothing showing in the edit box for the Body. Strangely when I went to edit the post again via WLW it still had the text of the post. I've no idea where it got it from (cache maybe), because I couldn't find it in the NewsArticles of NewsArticles_Pages tables (the Summary was blank in NewsArticles, and there was no page in the _Pages table).
Very strange, but worth you checking. For my other posts (4 - I'm just getting started), I split the post and removed the empty paragraph marks automatically inserted before the split (in HTML view), published, then removed the split, and posted again. This seemed to do the job.
Maybe worth trying to replicate...
Cheers
Roger
