Oh right, quick reply. Sorry. Yeah, it calls newreply instead of editpost, but it is the same idea. Unfortunately it's not really my area either.

Although I did create a "check for new replies" mod that has a similar issue. It displays a message if someone else replied to the thread while you were typing your reply. If I remember correctly, it works because the javascript that makes the "ajax" call gives up if it gets an error, and just goes ahead and reloads the page. So mayb yours could work the same way: use a hook in newreply.php, check for ajax=1 and for the post being modified, and if it is just exit the script (which will cause an error and make the page reload). I hope.
