After editing the title of a post, you are brought back to the topic, and the changes do not show until you go back to the topic listing and click on your topic again. This is minor of course...
Example: I edited the title of my post 'Fix for Preview Problem!' Changed it to 'Fix for Preview Problem?', after I edited and returned to the topic, it showed 'Fix for Preview Problem!'
The reason for this is that the Topic Title and Forum Title is passed in the URL. And the URL isn't changed when you change the topic.
I solved this in the Announcements MOD that I did by using Request.Form instead of Request.QueryString when editing an Announcement. That way if the Announcement Title was changed, it would reflect that in the little tree view on the top left of the page just underneath the Forum Graphic.
You'll see the same result when you move a topic from one forum to another.
