title: Javascript popup print page blocking the parent actions
body: <p>I have a parent page calling the child popup page to show the print page. After redirecting to print page If I close the the child page I can do other activities in parent page, but when I minimize my Child page (print page) and try some activity it is not responding, after closing the Child page what ever I did it is recreating.</p>
  
  <p>Code:</p>
  
  <pre><code>var chartDiv = document.getElementById('innerchartdiv');
  var outerContainerDiv = document.getElementById('outerContainer');
  var divToPrint = chartDiv.innerHTML;
  setTimeout(function(){
  var popupWin = window.open('', '_blank', 'width=800px,height=800px');
  popupWin.document.open();
  popupWin.document.write('&lt;html&gt;&lt;body align="center" style="margin:0% 17%;font-size:9px;"&gt;' +     chart+'&lt;/html&gt;');
  popupWin.document.close();
  popupWin.focus();
  popupWin.print();
  popupWin.close();
  </code></pre>
