When we're admin, it would be cool to have ability to edit a post even if the topic is closed. It's a little bit annoying to have to unlock, edit and lock again.
@Groberto From what I can tell here, there's no code that forbids a post editing attempt if the topic is locked... though perhaps I am looking at the wrong place.
What happens when you try to edit? Is the button missing from the front-end?
