Help with free shipping coupon

I have a free shipping coupon if you spend $74 in a certain category. I have the top set at deny and the categories to allow. If a customer is purchasing just from categories that are allowed, everything works fine. If a customer tries to just buy something not in those allowable categories, it denies the coupon. Problem lies when a customer buys $74 in an allowable category AND a product that is not allowed. The coupon still gives free shipping even though buying the product from the unallowed category shouldn't allow it to work. I need the coupon to be denied in this instance.

any ideas? These are shipping promos from specific manufacturers so it would be a direct loss to me on shipping if the coupon continues to work like this. I am on 1.3.6

At this time, there is not a qualification on the Free Shipping once the restrictions have been met ... to invalidate it if other Products are in the cart ...

Thanks for the response. At least I know I'm not missing something. I guess I'll keep with my current set up and manually add in shipping if they add in a product that doesn't qualify.

thanks again
