Are there any knowlegeable Agent users on this NG?
I've done something to Agent that causes it to display all messages as
single messages and not shown in message threads.
The built in Help has little info on "Threads" and I'm at a loss. Any
help greatly appreciated.

Right click the header for the Date column and select one of the
thread sort options.

Failing this, look in Help at:
Options Dialog, Navigation and Menus
Message Sorting Panel
