problem with Shipping Address

[naxos]

hello,

I have this problem: After logging in, you put a different shipping address than the billing address.
I make a 1 st order and the invoice is ok.
I want to make a 2 nd order in the same login session, but I want the 2 nd delivery is made ​​to the billing address, if I select the flag "Use billing address as shipping address" the sending is always done to the shipping address initially added, VM does not read the flag.


I have to logout and login again;  in this way, the shipping address initially entered is deactivated and I can proceed with the second order and send products to billing address.

It's a bug?

Thank you, naxos
