I've set the limit to 20 words in the theme settings, and adjusted the Maximum Node Height to 300 to accommodate this. However I've noticed that it seems to be ignoring the 20 word limit, letting the whole post show (in the content).

I'm running WP 1.3.2, and the latest version of Arras at www.franklinzoo.co.nz. I would be very grateful if anyone could let me know if I've missed something or could point me in the right direction to look.
