Side Box not showing sub categories

[Prime]

Hi,

I'd like my side-box menu to display the sub categories when the mouse hovers over the category.

My website is here:
http://primealternatives.com.au/cart/index.php

The top menu works fine when I select 'Products' > 'Massage Accessories' it shows the sub categories, but when selecting 'Massage Accessories' from the side menu it doesn't show the sub categories.

I do have the 'Layout Settings' option 'Categories - Always Open to Show SubCategories' set to "1".

Please assist.

Thanks

I also have the 'Product Listing' option 'Show SubCategories on Main Page while navigating' set to "1".

Zencart doesn't do that (subcategory list on hover) as a standard feature. I think there's a mod or two in Free Software Add Ons (above) that will add that feature.
