Hi @lat9,

I've received reports of a bug in the address processes during checkout. I tested this myself with a clean install of ZC 1.5.7d and OPC and can confirm I saw the same issues that were reported to me.

I have pasted the initial report as I received it.

1. If you only have 2 addresses in your address book and go to edit either the shipping or billing details, you don't get the drop down menu with the other address in it, you just have to fill out your details again. Ideally, if someone has 2 + addresses, the drop down should appear on both shipping and billing
2. If you have 3 + addresses, and you change your billing details,
your shipping address automatically changes. This shouldn't happen, you should be able to change your billing details and it not have an effect on the shipping address. The problem only occurs when you change the billing details. If you change the shipping address, the billing details do not update. Things to note:

* When you manually change the billing address at checkout, the
problem doesn't occur. It only seems to be when you are choosing from the drop down
* If you test this, when I initially added more addresses to my
account and then changed the billing details, the problem didn't occur. However, when you log out and back in, that's when you get the issue.
