1.Address book when correct contains 175 names and email addresses. After closing down Thunderbird and then restarting , there are 187 records. The additional 'bogus' records are similar to original records except the 'name' of the individual is the first part of the email address in the persons record e.g in addition to Steve Jenkins in 'name column of correct record has been added an additional record namely s.g.jenkins from the first part of his email address along with the same email address as the correct record. 2. Name in record lists do not correspond in all cases to the 'Display' title entered into the individuals record. 3. Details of certain fields in the individal records have become exchanged with another individuals details.e.g someone elses email address has been acquired from another an individuals record. 4. Sometimes , names do not appear on teh drop-down menu when inputting to a group but will then re-appear when the action is repeated. ...... ******* HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
