title: jStorage not persisting keys in IE9
body: <p>I can't get IE9 persist keys written by jStorage (the engine used being userData) (jQuery).</p>
  
  <p>The write/read (all-in-one) seems to work properly ; the getter function retrieves the correct value :</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  
  &lt;head&gt;
      &lt;script   type="text/javascript" src="jquery-1.7.2.min.js"&gt;&lt;/script&gt;
      &lt;script   type="text/javascript" src="jquery-json.js"&gt;&lt;/script&gt;
      &lt;script   type="text/javascript" src="jstorage.js"&gt;&lt;/script&gt;
  
      &lt;script type="text/javascript"&gt;
  
          alert ("Localstorage support : " + $.jStorage.storageAvailable() );
  
          alert ('Setting bar -&gt; aaa');
          $.jStorage.set('bar', 'aaa');
  
          alert ('Setting foo -&gt; bbb');
          $.jStorage.set('foo', 'bbb');
  
          var foo = $.jStorage.get('foo')
          alert ('Getting foo =' + foo );
  
          alert ( "index = " + $.jStorage.index() );
  
      &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>However, if I use the following to just retrieve the value, the index is empty and foo is null :</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  
  &lt;head&gt;
      &lt;script   type="text/javascript" src="jquery-1.7.2.min.js"&gt;&lt;/script&gt;
      &lt;script   type="text/javascript" src="jquery-json.js"&gt;&lt;/script&gt;
      &lt;script   type="text/javascript" src="jstorage.js"&gt;&lt;/script&gt;
  
      &lt;script type="text/javascript"&gt;
  
          alert ("Localstorage support : " + $.jStorage.storageAvailable() );
          var foo = $.jStorage.get('foo');
          alert ('Getting foo =' + foo );
  
      &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I don't use any webserver, the files are loaded directly from the filesystem (and I <em>do not want</em> to use any webserver).</p>
  
  <p>Any ideas ?</p>
