title: window.open() not working in IE11
body: <p>I've searched many links for my query. But couldn't get the one I want.
  Am using in <code>window.open(url, '_blank')</code> in my script on click of button(am not using any html here, I want it to be on button click only). Its working in Chrome, IE8. I want to open a new tab in the same window in <strong>IE11</strong>. I don't want to do any settings in Internet Options of IE. Because the script has to work in every system, if I go with manual settings the script won't run in all the systems where ever I test.
  Is there any bug with IE11 ?</p>
