Shopping cart module and popup window

[Setko]

If show popup window for adding a product in a cart is checked there is one problem.
In module Shopping cart i have show price/list of products set to NO, so there is only name for cart and number of products on the site. However, when you add a product in a cart and popup shows up, those 2 settings goes to YES, if you refresh your site again, everything is fine. It's not much of a problem, i set a display:none in css, but it's still a bug. The problem is only when you have popup window enabled.
Just to let you know about it.
