/*
activateActiveX
---------------
Purpose:  Dynamically replace any elements that will be affected by the new security feature in IE6/IE7 that requires a user to click certain types of elements to activate them before use.

Usage:  Include this file at the end of your html document using the following...
	<script language="JScript" type="text/jscript" src="activateActiveX.js"></script>
	


Since this script is in response to a software patent lawsuit, I feel it necessary to state the following...
