Ever since upgrading my cart from 1.3.9a to 1.3.9h, I've been having a nagging issue which I suspect is linked to the Stock with Attributes addon.

I have reinstalled the addon, but the problem continues.

Here's what happens:

Everything works fine, until the customer adds an item to their cart which is out of stock. If they don't remove that item immediately, everything else they add is labled "Out of Stock", regardless of its actual status.

As I said, I've reinstalled the Stock with Attributes add on, but the problem persists. Does anyone have any ideas where I might start looking? I'm getting desperate.

Thanks,

John
