    Smile Disable Function keys when running SWF simulation

    Hello all,

    I am creating a simulation in which the Function keys are used.

    I have stolen some Javascript to block the F1 --> F12 keys...
    ...but it ONLY works when the HTML page is in focus. When the SWF is in focus doesn't work.

    Does anybody have any ideas?
    ~ Thanks!!

    Code:
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title></title>
    <link rel="stylesheet" type="text/css" href="captivate.css" />
    <script src="standard.js" type="text/javascript"></script>
    
    <script type="text/javascript">
    	var nonChar = false;
    	var Combo = false;
    	
    	document.onhelp = new Function("return false;");
    	window.onhelp = new Function("return false;");
    	
    	document.onkeydown = function(e) { handleKeys(e); }
            	
    	function handleKeys(e)

    		if (!evt.stopPropagation)
