What steps will reproduce the problem?
1. new a GDesktopPane and add some larget (full screen size) widgets on it 
by addWidget() method.
1. new a DefaultGFrame and show it in modal mode.
2. the OverlayLayer mask the underlying components well at the first time
3. close the DefaultGFrame and new another DefaultGFrame  in modal mode.
4. the OverlayLayer shows below the desktop bar.

What is the expected output? What do you see instead?
add two line of code to OverlayLayer may solve the proble:

    public void show(String theme, int deep) {
        setStyleName("gwm-" + theme + "-ActionOverlay");
        RootPanel.get().add(this);
        DOM.setIntStyleAttribute(getElement(), "zIndex", DefaultGFrame
                .getLayerOfTheTopWindow()
                + deep);

        // Added by kelvin
        DOM.setStyleAttribute(getElement(), "position", "absolute");
        DOM.setStyleAttribute(getElement(), "top", "0px");
        // Added by kelvin

        setVisible(true);
    }
