[imp] address book lists

[a.k.a. James M. Jones]

I've set up horde, imp,  and turba, and am able to create a list in the 
address book, but when I try to send a message to the list, I select the list, 
click "To:", but the list does not get copied to the right box.  I can select 
individual addresses ok, but not a list; it simply will not go into the right 
box to be used.

I've scoured the archives and the net and have not found anyone else with this 
problem.  (Your forgiveness is requested if I missed the problem/solution.)

Any ideas?
