I'm using Atahualpa 3.4.3 and WP 2.8.5 for my news site.
Just noticed something: I created a post with a title. After publishing (or saving a draft), the title appears on the front page. The title also appears in the title fields of the Atahualpa Post Options box under the main editing box. If I then change the title in the title field of the main editing box and publish, the title does NOT change in the Atahualpa Post Options title fields. In fact, the new title will show up in the Recent Posts widget in the left sidebar, but the old title shows up in the center column, front page.
So if I want to have the new title appear everywhere, I have to remember to change it in the ATA Post Options fields as well as in the main title field. I haven't tested this in Ata 3.4.4 yet.
