Date: 06/02/2016 Enhanced Folding Category List for WordPress 2.8+
Try deleting any unused widgets from the "inactive widgets" section of the widgets dashboard and try again.
WordPress 2.8+ Simply drag the focal icon to your sidebar(s) as needed.
WordPress 2.3 - 2.7 Below your available widgets section, you should see a section asking "How many Folding Category widgets would you like?". Simply change the number in the box and click save. For some reason it does not always add extra widgets on the first attempt, but it works fine the second time.
