Multiple window opacity issue when open PDF inside iframe

[maksymg]

Hi,

We need to open a few pop up "edit doc" windows each of them consist of two (left & right) HTMLPanes/iframes:
- left one load indexing page doc info as HTML page (legacy system);
- right one load PDF from HTTP server (regular Adobe Reader browser plugin)

Everything opens fine, but when you try to move windows around, the top window header and left HTML portion become partially opaque when you move the window over the one of the bottom window's PDFs iframes.
Tested on Firefox 3.6.2, GWT 2.0, SmartGWT 2.1

   Canvas main;

   public void onModuleLoad() {
      //load a VB interface
      main = Canvas.getById("rootVLayout");
      main.draw();
   }

   private Window createDocEditWindow(int docId, int index) {
      HTMLPane indexHTMLPane = new HTMLPane();
      indexHTMLPane.setContentsType(ContentsType.PAGE);
      indexHTMLPane.setContentsURL("http://www.google.com");
      indexHTMLPane.setShowResizeBar(true);

      HTMLPane imageHTMLPane = new HTMLPane();
      imageHTMLPane.setContentsType(ContentsType.PAGE);
      imageHTMLPane.setContentsURL(REFERENCE TO PDF); 

      HLayout rootHLayout = new HLayout();
      rootHLayout.setWidth100();
      rootHLayout.setHeight100();
      rootHLayout.addMember(indexHTMLPane);
      rootHLayout.addMember(imageHTMLPane);

      Window window = new Window();
      window.setWidth(700);
      window.setHeight(700);
      window.setTop(10 * index);
      window.setLeft(10 * index);
      window.setCanDragReposition(true);
      window.setCanDragResize(true);
      window.setShowMinimizeButton(false);
      window.addItem(rootHLayout);
      return window;
   }

   void onSomeEvent() {
      Window win = createDocEditWindow(11, 1);
      main.addChild(win);
      win = createDocEditWindow(22, 2);
      main.addChild(win);
   }

Any suggestions?
