Its seems there is somthing going on with my .NK2 file. When I email a
contact initial he doesn;t appear then I go to my contact list add
him to the To: field and compose and e-mail my message. The next day
I start tyoping his name and his name doesn;t appear. can anyone shed
some light on this?

The NK2 file (the autocompletion cache) is COMPLETELY UNRELATED to your
Contacts. The NK2 file remembers addresses to which you've sent mail
regardless of whether or not they're in your Contacts folder.
