title: Python Pywinauto no control_identifiers or children in application
body: <p>Hey everyone I'm having a hard time automating a specific application. Using pywinauto I want to automate clicking, keypresses, etc. to login and benchmark this application but for some reason I can't find any control identifiers for this application. Am I doing something wrong? I used this same method with task manager and other applications and this works fine.</p>

  <p>Code:</p>
  
  <pre><code>import pywinauto
  app = pywinauto.application.Application()
  window_handle = pywinauto.findwindows.find_windows(title = u'Name of application')
  #print window_handle #makes sure to see if handle exists
  window = app.window_(handle = window_handle[0])
  print window.Children() #first approach
  print app.top_window_()._ctrl_identifiers() #second approach
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>&gt;&gt;&gt;[]
  &gt;&gt;&gt;{}
  </code></pre>
  
  <p>Has this happened to anyone before and has found a way around it? Should I just resort to using pywin32 instead? Thank you!</p>
