Widgetized Navigation changes the menu appearance

Hello,

Thank you for this plugin and support.

I installed and activated the plugin. Then I followed the directions and added one widget, in one column, to one menu item.

The plugin did more than adding the widget. It took over the entire menu appearance.

Here is a screenshot of what the original menu looked like:

And a screenshot of what happens using this plugin:

How can I add widgets to the menu but NOT change the menu appearance at the top level?

Thank you again for the support.

Chris
