the Textfields for the login are to big for their container. I took a screenshot using firebug. I was able to reduce the size of all textboxes. But failed so far to shrink only those two.
You should be able to set the width in your css file using the id of the text box inputs like #mod_login_username { width:50px or whatever; } and #mod_login_password { width:50px or whatever; }
