At the bottom are listed the 2 addresses for the account. If I move the dot to the unselected address and click Continue the page goes back up to the Form for adding a new address and highlights the fields in red. It forces you to create a new address it will not allow you to choose an existing one.

The same problem occurs if you click Change Address on the Step 2 of 3 Payment Information page for changing the billing address.
That's a problem that was introduced in the first zip of v1.5.5 which included some HTML5 validation rules on those fields, but didn't account for the use of radio-buttons to override the "required" text fields. The fix for that bug was posted here: checkout-address-page-bug and fixed in a subsequent zip release.

You may find the other fixes on that page helpful too.
