I'm wondering if anyone else can replicate this, as it is happening on two of my sites, but not here on xenforo.com. Using firefox 6.0.2. View a thread, and find a post that needs editing Click the 'edit' link Once the pop-up window has loaded, click the 'Use BB-Code Editor' button at the top right of the window. Give it second or two, the page auto-reloads to the forum index. This does not appear to happen in IE9.
