I have a problem with the ImageCommand icon in IE6. The icon does not display when the column has a rendering function attached, even if the function has a emty body (do nothing). żIs this a bug or there is any consideration about IE6 and ImageCommands?

Thanks in advance.

<ext:Column meta:resourcekey="colDescDetallada" DataIndex="DescripcionDetallada" Sortable="true">
  <ext:ImageCommand CommandName="Edit" Icon="NoteEdit">
   <ToolTip Text="Editar" />
 <Renderer Fn="DescripcionDetallada_Renderer" />
