I have several addressee groups. When I compile a group in a Category, i. e., Computer Club, and input the addresses of our 35 members, I see the category and see the member names in the box below the listing of all my contacts just fine.

After I send a message to that addressee group by placing the Category name on the Bcc: line (I use my address in the To: line), the message  goes out to those individuals. However, the next day when I open WLM and prepare to send an email to that same group, I place the name of that category in the Bcc: box and click on the plus sign only to find that the email addresses have disappeared.

I found that out the hard way when I received complaints that none of the club members were receiving the meeting notifications. When I go to that category to edit the names, I find that it is empty.

How do I fix this problem?
