scrolling problem with containers

[Warcaptain]

when you move the graalcontrol it causes scrolling problems... ie with this:

NPC Code:

---

//#CLIENTSIDE



function onCreated(){

  drawGui();

}



function drawGui(){

  TestWindow = new GuiWindowCtrl("TestWindow");

  with (TestWindow){

    profile = "GuiBlueWindowProfile";

    x=0;

    y=0;

    width=screenwidth;

    height=64;

    visible=true;

    canresize=false;

    canmove=false;

    canclose=false;

    canmaximize=false;

    canminimize=false;

  }

  GUIContainer.addControl(TestWindow);

  GraalControl.height=GUIContainer.height-64;

  GraalControl.y=64;

  GraalControl.horizSizing = "width";

  GraalControl.vertSizing = "height";

  TestWindow.vertSizing = "left";

}

---

this should display a screenwidth wide and 64 pixel high blue indow at the top and move the graal control down 64 (and shrinking its height 64 to fit) which it does but it has scrolling problems at the bottom
