title: Javascript window.blur()
body: <p>I have this piece of code:</p>
  
  <pre><code>window.addEventListener( "focus" , function(){
      window.console.log("focus");
  } , false );
  
  window.addEventListener( "blur" , function(){
      window.console.log("blur");
  } , false );
  </code></pre>
  
  <p>And if I run : <code>setTimeout("window.focus();",2000);</code> from firebug's console I get "focus" after 2 seconds but if I run <code>setTimeout("window.blur();",2000);</code> I don't get "blur".</p>
  
  <p>Could someone help me please? I don't understand it, it should work.</p>
