Can anyone please tell me why my invokeLater in the following code never
displays the JFrame I am trying to get it to display, and shows no
exceptions either? I am certain I must have somethign stupid and wrong here.
Thanks, Ike

public void putupreconnectnotice(boolean on){
        if(on){
            javax.swing.SwingUtilities.invokeLater(new Runnable() {
                public void run() {
                    connectionLost();
                }
            });
        }else{
            if(waitjframe!=null){
                waitjframe.dispose();
            }
        }
    }

    private void connectionLost(){
        waitjframe = new JFrame("Connection to server lost!");
        waitjframe.setSize(310, 75);
        waitjframepanel=new JPanel();
        waitjframepanel.setPreferredSize(new Dimension(300,60));
        waitjframepanel.setBackground(Color.WHITE);
       waitjframepanel.add(new JLabel("Attempting to reconnect"));
        waitjframe.getContentPane().add(waitjframepanel);
        waitjframe.pack();
        waitjframe.setVisible(false);
        waitjframepanel.grabFocus();
    }

Perhaps it's because your connectionLost method specifically calls
setVisible(false) on the frame?
