The PanPanel is visible control for panning the map North, South, East or West in small steps. By default it is drawn in the top left corner of the map.
If you wish to use this class with the default images and you want it to look nice in ie6, you should add the following, conditionally added css stylesheet to your HTML file:
<!--[if lte IE 6]> <link rel="stylesheet" href="../theme/default/ie6-style.css" type="text/css" /> <![endif]-->
