This bug seemed to start on 1.3-H build. I tried the following program on G build and it works fine, but on H and subsequent builds the tool tip is just a flicker where you can see it for a very brief moment and then it disappears.

Here is a simple program to re-create it:


--------------------------------- Cut Here -----------------------------------

import javax.swing.*;

public class TestToolTip extends JFrame {
    JPanel testPanel;
    JButton button;

    public static void main(String[] args) {
        new TestToolTip();
    }

    public TestToolTip() {
        testPanel = new JPanel();
        button = new JButton("Hello");
        button.setToolTipText("Hello There");

        testPanel.add(button);
        setContentPane(testPanel);

        setSize(300, 300);
        setVisible(true);
    }
}

---------------------------------- Cut Here -----------------------------------

Note: Be sure to use Kestrel 1.3-H build or up.
