title: IE: Can't submit form after selecting file programmatically
body: <p>I found that the only way to programmatically trigger 'Select File' dialog is by invoking click() function on the hidden input file control. 
  Tried this in Chrome, works perfectly. in IE, Select File dialog is displayed, but the form can't be submitted after the file is selected. 
  Here's the simplified code (input file is not hidden in this example):</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  &lt;form id="myform" action="test.html" method="post" enctype="multipart/form-data"&gt;
  &lt;input type="file" name="file" id="myfile" onchange="submit();"/&gt;
  &lt;input type="button" value="Browse File" onclick="document.getElementById('myfile').click()" /&gt;
  &lt;/form&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Looks pretty straightforward, can't see what IE doesn't like here...</p>
