title: Mootools Issue in IE8
body: <p>I am having an issue with Mootools. If you go to this page <a href="http://www.hanseninfotech.com/rtds" rel="nofollow">RTDS</a> you'll notice a login button in the top right. On all other browsers (IE9, Safari, Chrome, and Firefox) the login works fine but it doesn't work in IE8. IE says its an error related to moo tools but I don't really know what it means or how to fix it. The error is as follows:</p>
