User blog comment:Sarah Manley/New Editor Scheduled for Sitewide Release/@comment-1514297-20110919231421

Would be good to be able to search this thread to see if it's been reported - so apologies if already known bug - it seems that the new editor baulks at editing any pages in visual mode that have footnotes. It claims that the page is to complex to edit in visual mode and throws you straight into source mode....
