    From what I’ve read on websites, some of these should “in theory” work. The class accepts the message rather than broadcasting it to all parent windows (this is also the easiest way to work with extended controls).

    But for various reasons, the scroll is undoubtedly moving, and if you try to move it manually, it will just keep moving in the square to capture your every move.
