Doesn't hide app-specific pointers like Cross in Excel

Or reverse arrow in WordPad near the border or "hide whitespace" cursor in Word etc.

Do you know how to hide those? (AutoHideMouseCursor hides those, but it's not open source, so not sure how)

I don't know how, but guessing it requires to somehow mess with the target process directly. This is not safe (possible malware alert) and straightforward as hiding standard system pointers. I can try looking into it but cannot promise results.

I think a simpler solution without hooking anything could be to create an invisible GUI element, using the target window as its parent, and then invoking ShowCursor, that should steal the pointer from the active window, so something like this in AutoHotkey

!5::hide_mouse_pointer()
hide_mouse_pointer() {
  static isHidden := 0
   , guiBlock := Gui()
  if isHidden = 0  {
    MouseGetPos(,,&winID,)
    guiBlock.Opt("+Owner" . winID) ; make the GUI owned by winID
    DllCall("ShowCursor", "int",0)
    isHidden := 1
  } else {
    DllCall("ShowCursor", "int",1)
    isHidden := 0
  }
}

Nice trick, saved a lot of trouble. Thank you.
Made the update.

Thanks for the update!

I've noticed that if you change timeout then it stops working for app pointers (continues to work for regular pointers), restarting the target app (or MousePuff) fixes it
