At the end of the method it does this. "but.Location = new Point (x, y);".
The problem is that by pressing the directional arrow, it changes the location of the button and does not continue with the focus on the button it focuses on another button.

public class AnnoyingButton : Button {

  protected override bool IsInputKey(Keys keyData) {
    return keyData == Keys.Up || keyData == Keys.Down ||
           keyData == Keys.Left || keyData == Keys.Right;
  }

  protected override void OnKeyDown(KeyEventArgs args) {
    Point newLocation = Location;

    switch (args.KeyCode) {
      case Keys.Right:
        newLocation.Offset(1, 0);
        Location = newLocation;
        break;
      case Keys.Left:
        newLocation.Offset(-1, 0);
        Location = newLocation;
        break;
      case Keys.Down:
        newLocation.Offset(0, 1);
        Location = newLocation;
        break;
      case Keys.Up:
        newLocation.Offset(0, -1);
        Location = newLocation;
        break;
      default:
        base.OnKeyDown(args);
    }
  }
}

You attached the key handler to the button. You should (probably) attach it at the form level
