I'm really not sure when this problem started happening, but I'm guessing it happened when I upgraded to 1.3.7 a couple months ago. This is just the first time I've noticed it, and I'm not sure what to do to fix it. Basically, when a customer has created an account, and wants to create a new shipping address, after typing in all the relevant info and clicking Continue, the page reloads and says "You must select a country from the Countries pull down menu." and the Country drop-down is reset. So no one can create an additional shipping address. Has anyone else had this problem when upgrading to 1.3.7?

thanks.
