On my blog everything is up to date (both WP and P2) and I have this problem:
I always put a title on each post. But if I make an edit from the front page, as P2 permits, my title disappears and the title bar picks up the opening few words of the post body instead.
Often these are not what I want for a title.
I have to go into the admin screens and use the full-bore editor for this not to happen.
Is there a fix?
