This code displays a window of icons and text labels.
The idea is that the user clicks a label and then the
code takes appropriate action (I've not provided complete
code as it should be possible to substitute out the
missing bits).

To reproduce:

Display the frame - click and drag the window by
using the titlebar and then move the mouse directly
over one of the text labels.  The result will be a
rogue mouseClicked event.

NOTE:  The code currently contains a workaround (see
clickedMouse).

I suspect this is related to a previous bug -4039858

/**
	GUI representation of a palette object.
*/
public class PaletteGui extends Frame implements ComponentPaletteListener, MouseListener,
					WindowCloserCallback {
	boolean clickedMouse = false;

	Panel myPanel = new Panel();

	public PaletteGui() {
		super();

		// Register against a WindowCloser to process my window closed event
		WindowCloser myCloser = new WindowCloser(this, true);

		setBounds(0, 0, 1, 1);
		setVisible(true);

		myPanel.setBounds(getInsets().left, getInsets().top, 150, 64);
		myPanel.setLayout(new GridBagLayout());
		myPanel.setBackground(Color.lightGray);
		setLayout(new GridBagLayout());
		add(myPanel, newConstraint(GridBagConstraints.NORTHWEST, GridBagConstraints.NONE,
					0, 0, 1, 1, 0, 0));
	}

	public void componentRemoved(ComponentPaletteEvent e) {
	}

	public void componentAdded(ComponentPaletteEvent e) {
		LightweightPanel newPanel = new LightweightPanel();
		newPanel.setLayout(new GridBagLayout());
		newPanel.add(new BitmapCanvas(IconManager.getIcon(e.getComponentName())),
					newConstraint(GridBagConstraints.WEST, GridBagConstraints.NONE,
					0, 0, 1, 1, 2, 2));

		Label newLabel = new Label(e.getComponentName());


		newPanel.add(newLabel, newConstraint(GridBagConstraints.WEST, GridBagConstraints.NONE,
					1, 0, 1, 1, 2, 2));

		myPanel.add(newPanel, newConstraint(GridBagConstraints.WEST, GridBagConstraints.NONE,
					0, GridBagConstraints.RELATIVE, 1, 1, 0, 0));

		newLabel.addMouseListener(this);

		// Re-size panel
		setResizable(true);
		Dimension newDimension = myPanel.getPreferredSize();
		setBounds(0, 0, newDimension.width + getInsets().left + getInsets().right,
				newDimension.height + getInsets().top + getInsets().bottom);
		setResizable(false);
		validate();
	}

	private GridBagConstraints newConstraint(int anchor, int fill, int grdx, int grdy, int grdw, int grdh,
							int pdx, int pdy) {
		GridBagConstraints temp = new GridBagConstraints();

		temp.anchor = anchor;
		temp.fill = fill;
		temp.gridx = grdx;
		temp.gridy = grdy;
		temp.gridwidth = grdw;
		temp.gridheight = grdh;
		temp.ipadx = pdx;
		temp.ipady = pdy;
		return temp;
	}

	public void mouseClicked(MouseEvent e) {
		// Debug.message(Debug.GUI, "mouseClicked");
		if (!clickedMouse)
			Debug.message(Debug.GUI, "Discarded false click");

		clickedMouse = false;
	}

	public void mouseEntered(MouseEvent e) {
		// Debug.message(Debug.GUI, "mouseEntered");
	}

	public void mouseExited(MouseEvent e) {
		// Debug.message(Debug.GUI, "mouseExited");
	}

	public void mousePressed(MouseEvent e) {

		// Bugfix for problem with JDK 1.1.3 related to 4039858
		clickedMouse = true;
		// Debug.message(Debug.GUI, "mousePressed");

		Object source = e.getSource();

		if (source instanceof java.awt.Label) {
			Debug.message(Debug.GUI, "Component selected " + ((Label) source).getText());
		}
	}

	public void mouseReleased(MouseEvent e) {
		// Debug.message(Debug.GUI, "mouseReleased");
	}

	public void windowClosing() {
		Debug.message(Debug.GUI, "Palette Closing");
	}
}
