This submission contains two source files:
TreeCopy.java, and ConfigDialog.java.

Perform the following steps to demonstrate
the bug:
1) build and run the program.
2) From the "File" menu, select "New Window".
3) From the "File" menu in the new window,
   select "Configure".

In the dialog, the label text is drawn with
a white background. It should be drawn with
a grey background.

Here is TreeCopy.java:
import java.awt.*;
import java.awt.event.*;

/*
This code reveals a bug in drawing backgrounds for
labels.
*/

public class TreeCopy extends Frame implements ActionListener
{
TextField tfRoot;
ConfigDialog configDlg = null;
MenuItem miConfigure = new MenuItem("Configure...");
MenuItem miRun = new MenuItem("Run");
MenuItem miStop = new MenuItem("Stop");
MenuItem miExit = new MenuItem("Exit");
MenuItem miNewWindow = new MenuItem("New Window");
static int windowCount = 0;

public TreeCopy(int windowNum)
{
super("TreeCopy Window #" + Integer.toString(windowNum));

MenuBar mb = new MenuBar();

}

}
}

}
}


Here is ConfigDialog.java:
import java.awt.*;
import java.awt.event.*;

public class ConfigDialog extends Dialog implements ActionListener
{
public Button okButton;
public Button cancelButton;
Label l2;

public ConfigDialog(Frame parent)
{
super(parent, "Configuration Dialog");

okButton = new Button("OK");
cancelButton = new Button("Cancel");

// When the dialog is first made visible in a
// secondary Frame, the background for the
// label will be white instead of grey.
Label l2 = new Label("This is a label:");

setLayout(new FlowLayout());

add(l2);
add(okButton);
add(cancelButton);

okButton.addActionListener(this);
cancelButton.addActionListener(this);

pack();
}

public void actionPerformed(ActionEvent ae)
{
dispose();
}
}
