I am using v1.3.8 from a new installation.

We are getting an intermittent problem. From time to time, a person will select a product and complete some attribution information for that product and add it to their cart. When they go to the cart to checkout, they find someone else's attributes on the item in the cart. The only way they can proceed is to delete the item from the cart and start again.

This might be something that happens when we are having higher volumes (like 20 orders an hour or something), but that's not a hard fact.

Sometimes we end up with people not noticing and proceeding with paying for their order. This gets us into refunds, etc.

The whole thing makes our order site look pretty shaky and kills confidence in our customers who have encountered this.

Has anyone got any idea what is going on with this?
