 If you add the following code as a plugin or to your functions file, the
 category dropdown on the Posts edit screen will select the category
 instead of defaulting to 'View all categories'.

 {{{
 add_filter( 'pre_get_posts','my_posts_query' );

 function my_posts_query( $query ){

 $query->set( 'category__in', array(1) );

 return $query;
 }
 }}}

 I tried changing the query variable to category NOT in to test and it
 correctly defaults to 'View all categories'.

 The above code works properly in 3.0.4.
