title: PyWinAuto trouble clicking the Next Button
body: <p>This code gets the first window from InstallShield.</p>
  
  <pre><code>from pywinauto import application
  from pywinauto import findwindows
  
  app = application.Application()
  
  app.start("MyInstallShieldApp.exe")
  
  time.sleep(15)
  
  hwnd = findwindows.find_windows(title=u"InstallShield Wizard", class_name="MsiDialogCloseClass")
  print ("|", str(hwnd), "|")
  dlg = app.Window_(handle=hwnd).Wait("enabled", timeout=25, retry_interval=0.5)
  </code></pre>
  
  <p>Now I want to click the Next button. Swapy says that the Next button has the text '&amp;Next >' and the Button number is 1. But none of these click statements have any effect.</p>
  
  <pre><code>dlg.Click("Next")
  
  dlg.Click(coords=(977, 711))
  
  dlg.Click(button="left")
  </code></pre>
