Stop the Frame from being able to be dragged

Question

Hi all
I was hoping that someone could tell me how to stop the frame from being dragged
while a dialog is showing.
I am using this code to call the dialog.
When is is visible I can still click and drag the frame behind it.
I want to set it so you can not drag it until the dialog has be closed.
    public void runStartup() {
        Login dlg = new Login(this, "Login", true);
        Dimension dlgSize = dlg.getPreferredSize();
        Dimension frmSize = getSize();
        Point loc = getLocation();
        dlg.setLocation((frmSize.width - dlgSize.width) / 2 + loc.x,
                        (loc.y + 22));
        dlg.setModal(true);
        dlg.pack();
        dlg.show();
    }
