title: SendKeys doesn't always work
body: <p>I am using <code>.SendKeys()</code> in Excel VBA to send key strokes to an external window that I am making active using shell <code>.AppActive</code> method. The problem is that <code>SendKeys</code> is simply not behaving consistently and is sometimes sending the keys and sometimes not. I think it has something to do with storing the keys in the buffer according to MSDN documentation.</p>
  
  <p>How does one get around this?</p>
