Back from vacation, and I made this change so that I could make drafts and click the "advanced editing" button without creating a new thread. Basically, you should only create a new thread if you publish.
Find in wp-admin/post.php
Code:
// VB Bridge Start
if ($vb_bridge) {
if ($post_title == "") {
return;
}
and replace it with
Code:
// VB Bridge Start
if ($vb_bridge && $post_status=="publish") {
