Not stopping purchase of out of stock items

[rogerh]

I just finished upgrading a clients site from 1.3.7 to 1.3.8a. I've applied all the security patches. The site uses the xGiftwrap Module and the Stock by Attributes module. I'm not sure if my problems are related to the add-ons, but since they are there I thought I should post in this forum.

Major issue:
Shoppers are able to go through the purchase process and buy products that are out of stock. When an out of stock product is placed in the cart, the red box warning about something being out of stock shows, but nothing in that warning, nor by the product indicates which product is out of stock and if you continue on it just lets you check out.
Any ideas on how to fix this?

Very minor issue:
In the admin under configuration, the xGiftwrap Manager link shows up 5 times. Only the top one has anything in it. The other 4 are empty. How might I get rid of those 4 empty links?

Roger, what do you have in Admin > Configuration > Stock > Allow Checkout?

Allow customer to checkout even if there is insufficient stock

This should be set to False.

I have that set to false. That's what's annoying. It still letting customers check out anyway.
