Shopping cart redirection bug cs-cart 4.0.2

I've found that redirection to shopping cart doesn't work. The option in the admin settings “[color=#333333]Redirect customer to the cart contents page”. I've tried on 2 different installations on 2 different servers and the same, when user click add to cart always only the notification popup shows then it hides and the users stays on the same product/category page he was?[/color]
