I'm using the latest edit-comments.php from the CVS Last updated 2/13/2004.
On line 32. Shouldn't it be "$comments = $wpdb->get_results("SELECT * FROM $tablecomments ORDER BY comment_date $commentorder DESC LIMIT 20");"
Instead of "$comments = $wpdb->get_results("SELECT * FROM $tablecomments ORDER BY comment_date $commentorder LIMIT 20");"
Without DESC it was listing comments from 4 years ago first..
