links: ajax working and rel="external" freezing

links: ajax working and rel="external" freezing

scenario:on index page there are several internal links and one external link.
 
the moment after the app loads on playbook the ajax links work when clicked.
If I choose to click the external target link  the moment after the page loads the app freezes.
 
On a second and third opening of the app, the external link works.
 
only script associated with external link is:
 
$('a[target="_blank"]').live( 'click', function()
{
  if ( window.blackberry )
  {
   alert( 'Opening data center' );
   var args = new blackberry.invoke.BrowserArguments( $(this).attr( 'href' ));
   blackberry.invoke.invoke(blackberry.invoke.APP_BROWSER, args);
   return false;
  }
  return true;
