If you preview an existing node, that is a book, the following error message occur:

warning: array_key_exists(): The second argument should be either an array or an object in /home/www/ldpt.org/httpdocs/sites/all/modules/BookMadeSimple/book_made_simple.module on line 405.

This does not happen on newly edited nodes in preview mode.

Right.

Could you change the line 404 in the book_made_simple.module file : 

            if (variable_get('book_made_simple_hide_default_add_child',true)) {

by

            if (($node->links) && variable_get('book_made_simple_hide_default_add_child',true)) {

or get the new version (2.1b) at http://code.google.com/p/mmr-drupal-modules/wiki/BookMadeSimple
