Problem  

Bug ID: 5017762 

After you have performed an installation to update an earlier version of the Java Desktop System the Input Method Switcher applet is not added to the default panel. A symptom of this problem is that boxes are attached to windows.

The default panel configuration on Java Desktop System Release 2 is different from earlier releases of the Java Desktop System. You might experience this problem if you log into an earlier version of the Java Desktop System.

Solution  

Right-click on a panel, then choose Add to PanelUtilityInput Method Switcher.
