Keystrokes ignored when checking opener?

    When typing in text fields in my web page I noticed random keystrokes are
    occasionally skipped. You sometimes have to type a while before it happens.
    I traced this down to a function we are using to check if the opener is still
    open. Included is a simplified version of my problem. Any insight would be
    appreciated.

    Opener File
    
<html>
<head>
<title>Example</title>
<script>
function initForm()
{
  window.open("checkopener.html", "test");
}
</script>
</head>
<body onLoad="initForm()">
</body>
</body>
</html>
    HTML:
    File Checking opener with textbox
    
<html>
<head>
<title>Example</title>


<script>

function checkOpener()
{

  if (opener == null || opener.closed)
  {	
	self.close();
	return;
  }
 
  setTimeout("checkOpener()", 5); // value is set low to illustrate problem
}

function initForm()
{
  checkOpener();
}
</script>
</head>
<body onLoad="initForm()">
<center>
<input type="text" name="txtfield"></input>
</center>
</body>
</body>
</html>
