Hover over the blue rectangle to reveal the login panel. It works exactly how I'd like it to, with the exception that if you double-click one of the input forms to reveal the previously-entered usernames, by hovering over one of the suggested usernames the panel fades away...jQuery thinks my mouse has left the div when it actually hasn't.
Has anyone encountered anything like this before? Anyone know a fix?
Thanks.
