When I add someone in Yahoo Messenger, It goes to my address book ! how can I move it to contact list?

• I created a new yahoo account last day and I started to add my contact list of my old account. after I added some, when I add other contacts they go to address book. I want them at my contact list groups. how can I move them to main contact list ??

• Answer:

  You can double click it and add user after the pop up message window, but for now YM has this problem anywhere that prolonged my headache, once you add a contact, it prompts you that the Operation may have succeeded Please check your messenger list later, and for days now, does not put my added contact in YM contact list maybe in address book and stay there for long. You can try deleting your IE temp files, cookies and history, maybe it works for you, i tried this and gives me intermittent result, i can add one contact but not for the second attempt.
