WP-Cumulus shortcode not working in sidebar

Hi all,

I have set WP-cumulus widget up and running perfectly. I just want to add another widget by using text/html widget & [wp-cumulus] shortcode but it doesn’t work. The settings are OK under Settings > WP Cumulus and the tagcloud works fine in posts or pages.

So does anybody know how to put or what to set for the shortcode to be working in a text/html widget?

Thank you in advance…
