Details
Lets say you create a top level window derived from Swing JFrame (version of
swing doesnt matter).
Lets say there are three Textfields 'A', 'B' and 'C' in a panel inside that
window. I click on 'A' and then on 'B'. Now, instead of 'B' having the focus,
'A' has the focus. So, if something is typed in, it will get put in 'A' rather
than 'B'. Clicking twice on 'B' gives it proper focus. This happens with all
components including menus, JTrees, JTables etc.
If I click on 'A' anbd then 'B', 'A' retains focus. If I click on 'C' now, 'B'
will get focus. and if 'A' is clicked on, 'C' will get focus. Thus the component
which has a previous mouse clicked on it will get focus and not the component on
which the current mouse click occurs.
The following is sample code:

public class TestFrame extends JFrame implements ActionListener
{
public TestFrame()
{
Container pane = getContentPane();
pane.setLayout(new BorderLayout());
TestPanel tPanel = new TestPanel();
pane.add("Center", tPanel);
Button closeBtn = new Button("Close");
closeBtn.addActionListener(this);
Panel bottomPanel = new Panel();
bottomPanel.setLayout(new FlowLayout());
bottomPanel.add(closeBtn);
pane.add("South", bottomPanel);
pack();
}
public void actionPerformed(ActionEvent e)
{
setVisible(false);
}
}

This was caused by not calling JMFrameMouseOver on top level frames. Swing seems
to need to get mouse enter/exit events to do proper event delivery. I've got a
fix for this.
