WordPress MU

I posted my problem already to this thread to the worpress-forum, but i want to try it also here:
http://wordpress.org/support/topic/271030?replies=8

the updated version of the domain-mapping-plugin works fine an reduce the SQL Queries, but i have one problem:

I use a plugin with the following code to display content from another blog to my users:

switch_to_blog('38');
$post_id = 162;
query_posts('page_id=' . $post_id);
while (have_posts()) : the_post();
	the_title();
	the_content();
endwhile;
restore_current_blog();

After aktivated the "new" Version of the plugin, the code above doesen't work anymore and my plugin displays only the_title, but not the_content - only "NA".

Any Idea ?

Thx
