I have several Contact Categories containing groups of people I like to send
messages to.  I used to be able to highlight that Category and click in the
BCC area and they entered as +that category name. For some reason that's not
working anymore.  I can click on the BCC which opens my contact list and
highlight a category and it places it in the BCC area when I choose that.
It shows like "+madeupname".     After sending the message to myself and to
the group as BCC  I check the Sent folder and check the message to insure
those contacts show in the BCC area.  Nothing is there.  So I tried putting
nothing in the To: area and only the Category name in the BCC box.  It said
it can't send a message because nothing is listed in To:..CC:....or Bcc.

My email sends and receives OK with individual email addresses. My problem is that category does not work. If I copy and past contacts into a NEW category, it will work, but when I get out of mail and back in again later the same new category will not work to send mail to all the addresses contained.
