[SOLVED] Show Most Recent Post on Page (&YAPB Plugin)

Hi all,

I have a horrible feeling there's a very easy answer to this.

http://www.jonrouston.com/testblog/
I have the options in 'reading' set to display a static front page and then the 'photoblog' page to display the most recent posts with the number of posts set to one However, that page currently shows an archive? list of the most recent posts: http://www.jonrouston.com/testblog/?page_id=27

Whereas I would like it to show the most recent single post, i.e. when people click on 'photoblog' I would like them to see this: http://www.jonrouston.com/testblog/?p=155

Is there a way to display the single most recent post on that page? And is this a YAPB or a Atahualpa issue/ (or me being an idiot issue?)

Thanks in advance for any help

Jon
