galaxy 3 tablet - yahoo mail problem

[geoffinscottsdale]

New boy here finding my way around first tablet. When I try to forward a yahoo mail, I can't access the contacts list so have to input the whole e-address, rather than scroll the list and click on it. But the full list is there if I go to yahoo contacts. Do I need to set something up to link the contacts to the forwarding function ? Help appreciated. Thanks
