Hi Prof Ferris,

I've just now (today) seen this behavior.  It has
been submitted to Sun as a bug.  Once they release
a patch, we'll apply it to resolve this behavior.  

In the meantime, here's how to do what you'd like.

1  Login to Communications Express (the email
program).
2  Press Compose (this will popup a compose window)
3  Press the "to" button (in the compose window)
4  This will take you to your address book to
select names or groups.  Check the boxes you wish.  
5  Once you have you selection, press "Add recipients"

Your message is now addressed and ready for you to
type.
