title: Pyautogui don't work in game window
body: <p>I'm making some tests using Pyautogui on games.
  But in those games that change your cursor and fullscreen games, none of the methods work.</p>
  
  <p>I'm trying now on Ragnarok Online.</p>
  
  <p>I tried:</p>
  
  <pre><code>pyautogui.click()
  pyautogui.moveTo(x, y, time)
  pyautogui.moveRel(x, y)
  </code></pre>
  
  <p>None of them works when inside the game window. They work fine outside.</p>
  
  <p>Is there a way to make it work? Or another library that I could use?</p>
  
  <p>By the way, <code>win32api.SetCursorPos((x,y))</code> also doesn't work.</p>
  
  <p>Thanks.</p>
