Disabling "Buy Now" for items out of stock.

[Axe]

If the item number available is "0", and I list all the products in a category, it shows as there being 0 available, but it still allows the user to buy, and if they view that product specifically, again, they are able to buy.

Is there a way to disable this?

Is there also a way to have it removed from being randomly displayed in the "New Products" block if it's sold out (but still a "new product")?

go to /admin/configuration.php?gID=9
