Echo Web Framework

I have a TableEx with row selection enabled. Each row contains a label and a button.
Under Firefox, the button generates a row selection event instead of a button event.
However under IE, clicking on the button generates a button event. This is the behaviour I'm after.

The echo2 Table also generates action events.

Here is some code to reproduce the problem.
It displays two tables, each with a single row containing a label and a button.
The first table is an echo2 Table, the second an EPNG TableEx instance.
Clicking on the label in both should produce a popup saying "Row selected".
Clicking on the button should produce a popup saying "Button pressed"

public class TableExTest extends ContentPane {

    public TableExTest() {
        Column column = new Column();
        column.setCellSpacing(new Extent(50));
        column.add(init(new Table()));
        column.add(init(new TableEx()));
        add(column);
    }

    private Component init(Table table) {
        DefaultTableModel model = new DefaultTableModel(2, 0);
        TableCellRenderer render = new TableCellRenderer() {
            public Component getTableCellRendererComponent(Table table,
                                                           Object value,
                                                           int column,
                                                           int row) {
                if (value instanceof Component) {
                    return (Component) value;
                }
                return null;
            }
        };
        table.setDefaultRenderer(Object.class, render);
        table.setSelectionEnabled(true);
        table.setRolloverEnabled(true);
        table.setRolloverBackground(Color.BLUE);
        table.setBorder(new Border(1, Color.BLACK, Border.STYLE_SOLID));

        table.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                new Popup("Row selected");
            }
        });

        Button button = new Button("a button");
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                new Popup("Button pressed");
            }
        });
        model.addRow(new Object[]{new Label("a label"), button});
        table.setModel(model);

        Column column = new Column();
        column.setCellSpacing(new Extent(5));
        column.add(new Label(table.getClass().getName()));
        column.add(table);
        return column;
    }

    class Popup extends WindowPane {

        public Popup(String title) {
            setTitle(title);
            setModal(true);
            Window root = ApplicationInstance.getActive().getDefaultWindow();
            root.getContent().add(this);
        }
    }
}

This occurs using both the released echopointng echopointng-2.1.0rc5.jar and CVS HEAD
