When I go into AR-A and click the CO button at the bottom to get the customer's contacts, the Add New button is disabled. Nothing I do has gotten it to enable, including typing something in the search bar, changing the Sort By (BTW, there is a blank field in the drop-down and if you choose that Evo freezes), clicking on different contacts, and opening and closing a contact.
Possibly related, the first time you open Contacts the Drill Up button doesn't appear, but subsequent times the button does appear.
