title: window.open opens two popup windows in IE
body: <p>I'm getting a really strange behaviour in IE8.</p>
  
  <p>I have a simple javascript function to create a popup window. The popup window is created ok, but the parent window forwards to a completely blank window that just prints [object]. I have to hit the back button to get back to the original page.</p>
  
  <pre><code>&lt;a href='javascript:window.open("http://endic.naver.com/search.nhn?query=In&amp;searchOption=entry_idiom","Dictionary","width=500, height=500")' target="_blank"&gt;Click me&lt;/a&gt;
  </code></pre>
  
  <p>There is no problem in Chrome, just IE. How can I get rid of this annoying behaviour?</p>
