Search for

<script type="text/javascript">
<!--
function log_out()
{
	ht = document.getElementsByTagName("html");
	ht[0].style.filter = "progid:DXImageTransform.Microsoft.BasicImage(grayscale=1)";
	if (confirm('$vbphrase[sure_you_want_to_log_out]'))

  bo = document.getElementsByTagName('body');
  bo[0].style.filter = 'Alpha(opacity="30")';
  bo[0].style.MozOpacity = '0.3';
  bo[0].style.opacity = '0.3';

  if (confirm('$vbphrase[sure_you_want_to_log_out]'))
  {
    return true;
  }
  else
  {
    bo[0].style.filter = 'Alpha(opacity="100")';
    bo[0].style.MozOpacity = '1';
    bo[0].style.opacity = '1';

    return false;
