     /**
         * Handle {@link #urlLabelText} to change color if {@link
java.net.URL} displayed is not {@link #homeURL}
         */
        private void handleURLLabelText() {
            if (SimpleBrowser.this.getURL() != null &&
                    SimpleBrowser.this.getHomeURL() != null &&
                    !
SimpleBrowser.this.getURL().equals(SimpleBrowser.this.getHomeURL())) {
                SimpleBrowser.this.urlLabel.setForeground(Color.RED);
                if (!this.hasAddedURLLabelMouseAdapter) {
                    // THIS IS TO ENSURE ONLY ONE MouseAdapter
mouseAdapter IS ADDED TO JLabel SimpleBrowser.this.urlLabel
                    this.hasAddedURLLabelMouseAdapter = true;

SimpleBrowser.this.urlLabel.addMouseListener(mouseAdapter);
                }
                SimpleBrowser.this.urlLabel.setToolTipText("Click onto
\"" + urlLabelText +
                        "\" to set \"" + getURLPath() + "\" as your
default homepage");
            } else if (this.hasAddedURLLabelMouseAdapter) {
                // THIS IS TO ENSURE THE RE-ADDING OF MouseAdapter
mouseAdapter
                this.hasAddedURLLabelMouseAdapter = false;

SimpleBrowser.this.urlLabel.removeMouseListener(mouseAdapter);
                SimpleBrowser.this.urlLabel.setToolTipText(null);

SimpleBrowser.this.urlLabel.setForeground(Color.BLACK);
            }

SimpleBrowser.this.urlLabel.setFont(SimpleBrowserGlobals.FONT);
            SimpleBrowser.this.urlLabel.repaint();
        }
[/code]

I want to always be able to repaint the JLable
SimpleBrowser.this.urlLabel, however, on occasions while its
ToolTipText is always set with a value (or null), and while I can add
or remove its MouseListener, I can't seem to always change the color
back from red to black (though I can always change it from default
black to red).

I thought using repaint() would ensure that the changes to the JLabel
would take place, but unfortunately it does not, not even when I
invoke:

[code]
     /**
         * Handle {@link #urlLabelText} to change color if {@link
java.net.URL} displayed is not {@link #homeURL}
         */
        private void handleURLLabelText() {
            if (SimpleBrowser.this.getURL() != null &&
                    SimpleBrowser.this.getHomeURL() != null &&
                    !
SimpleBrowser.this.getURL().equals(SimpleBrowser.this.getHomeURL())) {
                SimpleBrowser.this.urlLabel.setForeground(Color.RED);
                if (!this.hasAddedURLLabelMouseAdapter) {
                    // THIS IS TO ENSURE ONLY ONE MouseAdapter
mouseAdapter IS ADDED TO JLabel SimpleBrowser.this.urlLabel
                    this.hasAddedURLLabelMouseAdapter = true;

SimpleBrowser.this.urlLabel.addMouseListener(mouseAdapter);
                }
                SimpleBrowser.this.urlLabel.setToolTipText("Click onto
\"" + urlLabelText +
                        "\" to set \"" + getURLPath() + "\" as your
default homepage");
            } else if (this.hasAddedURLLabelMouseAdapter) {
                // THIS IS TO ENSURE THE RE-ADDING OF MouseAdapter
mouseAdapter
                this.hasAddedURLLabelMouseAdapter = false;

SimpleBrowser.this.urlLabel.removeMouseListener(mouseAdapter);
                SimpleBrowser.this.urlLabel.setToolTipText(null);

SimpleBrowser.this.urlLabel.setForeground(Color.BLACK);
            }

SimpleBrowser.this.urlLabel.setFont(SimpleBrowserGlobals.FONT);
            SimpleBrowser.this.urlLabel.repaint();
            SimpleBrowser.this.topPanel.validate(); // CONTAINS
urlLabel
            validate(); // SimpleBrowser ULTIMATELY EXTENDS JFrame
        }
[/code]

Suggestions?
Thanx
