If you ever lose an edit (such as if the database gets locked half way through an edit, or it fails due to losing internet connection), it is worth trying to use the browser back button to the "submit" page, and try again, or if that fails, go back another step to the edit page. Sometimes I find that my work in progress is still there (but not if you try and edit the page again, it has to be done with the browser back button).
