title: Change mouse cursor across environment with AutoIt
body: <p>I'm hoping this is feasible... I made a program using AutoIt that resides in the system tray. One of the tray items runs a function that waits for the user to click on a window to get the window title (it can be any window, not necessarily one made from AutoIt. This part works flawlessly.</p>
  
  <p>I would like for the function to change the mouse cursor to the cross while waiting for the user's click. I have tried using GUISetCursor(3), but from my understanding this only changes the cursor for an AutoIt GUI window.</p>
  
  <p>How could I go about changing the mouse cursor for the user's environment, not just for an AutoIt window?</p>
