I've yet to see this work properly - based on my IP address (through my ISP:  CenturyTel.com). Is there a way to force this?

My users are all very local. So I would also be interested to find out a way to provide a default Country, City, State and zip code since these will be common among all but visitors.

Finally, when one chooses Country of United States, the cursor focus (tab stop) does not advance to the State field, forcing all users to switch from keyboard to mouse and back. Not critical, but ackward and this is something every new user gets to see...

This is deal with by the big boys at:

Their hack is:

"open up Address.ascx.vb and comment out the following lines then rebuild DotNetNuke the problem is corrected.

Page Load Event

612 <--                           If _Country = "" Then
613 <--                               cboCountry.SelectedIndex = 0
614 <--                           Else
615                                   If Not cboCountry.Items.FindByText(_Country) Is Nothing Then
616                                       cboCountry.ClearSelection()
617                                       cboCountry.Items.FindByText(_Country).Selected = True
618                                   End If
619 <--                           End If

632 <--                               If _Region = "" Then
633 <--                                   cboRegion.SelectedIndex = 0
634 <--                               Else
635                                       If Not cboRegion.Items.FindByText(_Region) Is Nothing Then
636                                           cboRegion.Items.FindByText(_Region).Selected = True
637                                       End If
638 <--                               End If

Cathal says those lines are there for a reason, but until it is fixed this may work better...
