Redrawing a JComboBox

I have a JComboBox whose values change dynamically. This all works OK except that the size of the box doesn't change. If I resize the browser window then the applet refreshes itself and the box resizes itself too.

This problem only appears to happen in the applet so was wondering if anyone can suggest how to make the box resize itself automatically. Here is the code that I'm using:

You could call the Applet's invalidate method to notify it that the layout is no longer valid, and that it should repaint itself.
