title: Autohotkey .exe runs in XP, not in Win8
body: <p>I created an .exe using AutoHotKey.  I created it in Windows XP.  I've pushed it to some other users who are using later versions of Windows (Vista and/or 8).  The .exe is not working in their systems.  I don't see any activation of windows or any keystroke functions.<br>
  The .exe is opening windows and inputting keystrokes in XP.<br>
  Thank you</p>
