Auto draft pages

To delete these pages you need to use a MySQL front end, go to the posts table, sort on post_status and all the auto-drafts will come to the top for ease of deletion. Seems to be a WP core problem – every time I login or switch to the dashboard page an auto draft is created unless there is one in the posts table already. Search Unleashed finds them, which is a further embarrassment, and duplicates can be created.
