  <p>I'm getting the error that the MyFrame object has no attribute istream. I am not sure why this is true because even in PyScripter under the code explorer, it lists istream as an attribute of MyFrame. I have a feeling I am missing something very fundamental here. Any thoughts?</p>
  
  <p>(BTW, Ignore the indentation errors, its due to the code block formatting.)</p>
