When I type an address that is not in my contact list I get the (no matches found) window and cannot send the email. I do not want that address in the contact list as I only want to send the message to that person once. I was able to send with NO problems on my old computer running on Vista. Have looked though all the blogs, help files, etc and have found absolutely nothing relating to this problem. Am running Windows 7 and Windows Live Mail. I think I like the old email program better. Never had this problem then.
