On order information page during checkout process in “Payment information” block I see checkbox “My billing information is the same as my shipping information.” and it’s checked when page is opened first time. If I uncheck it I get drop-down for selecting some other address from address book or creating new one. But what ever option I choose from that drop-down block just closes again and checkbox becomes checked again?!?
Is that normal behavior or it's is a bug? Should the block stay open if different address is selected?
In some cases it works well after all. I.e. for anonymous user. But for some user accounts it always works wrong.
