[Plugin: WP-BANNERIZE] Widget not wrapped in a DIV

I have several dynamic widgets setup in my functions.php file with the “before_widget” set so that all widgets are wrapped in DIVs with IDs and classes. This works for every plugin widget that I use except for WP Bannerize. I want the WP Bannerize widget to automatically put the UL inside of a DIV like every other widget does. However, it is not doing this. Instead it simply puts the UL in the sidebar by itself. This makes it more difficult to setup standard CSS rules for. I know I can manually add a DIV around the UL each time I add a widget but I am developing this theme for a friend and he shouldn’t have to remember to do that since this is standard WP functionality that works with other plugins. Please help.
