[O] Agenda view: ignoring everything that is DONE

[Chris Wallace]

I want to include in my agenda only things that are TODO, or are 
scheduled and not marked DONE, or have a deadline and are not marked 
DONE.  This is how agenda worked a year ago before I went on maternity 
leave, and now something has changed and I am seeing lots of DONE tasks 
which had a deadline -780 days ago.

I have tried removing all org customisations relating to the agenda and 
todo list, and have read the agenda part of the manual, but I can't get 
this to work.

Can anyone help?

Thanks, Chris.
