 This is reproducible in at least IE8 and FF 13.0.1, WordPress 3.4.1, and
 at least two separate domains.

 Problem: We have a least two sites which have custom post types and
 taxonomies originally added by the Custom Post Type UI plugin, in which we
 are unable to add new taxonomies to. After disabling all plugins and
 putting the post type/taxonomy code directly into the functions.php file:
 we are still unable to add new taxonomies.

 Reproduction: 1. Add a custom post type and a custom post type taxonomy.
 Add new custom post type "entry/post" from the admin menu or from the
 Dashboard sidebar. If is a hierarchical custom post type taxonomy, add a
 new custom post taxonomy. When the "Add New [Taxonomy]" button is pressed,
 the entered name in the taxonomy text field stays present, the add button
 seems to disappear from its location, and the add button is now displayed
 at the end of the custom post taxonomy list. The new taxonomy has not been
 added. (see image attached)
 2. Add a custom post type and a custom post type taxonomy. Add new custom
 post type "entry/post" from the admin menu or from the Dashboard sidebar.
 If is a hierarchical custom post type taxonomy, which already has taxonomy
 present, check several taxonomies. You will notice that there is "lag" in
 selecting these current taxonomies (IE8 at least).
 3. Although I have not been able to reproduce this, a client has mentioned
 that on an add custom post page where there is custom post taxonomy, the
 page is unusable and can eventually crash in IE8.

 Example functions.php
 {{{

 register_post_type('events', array(     'label' => 'Events','description'
 => '','public' => true,'show_ui' => true,'show_in_menu' =>
 true,'capability_type' => 'post','hierarchical' => false,'rewrite' =>
 array('slug' => ''),'query_var' => true,'supports' =>
 array('title','editor','excerpt','trackbacks','custom-
 fields','comments','revisions','thumbnail','author','page-
 attributes',),'labels' => array (
   'name' => 'Events',
   'singular_name' => 'Event',
   'menu_name' => 'Events',
   'add_new' => 'Add Event',
   'add_new_item' => 'Add New Event',

   'search_items' => 'Search Events',
   'not_found' => 'No Events Found',
   'not_found_in_trash' => 'No Events Found in Trash',
   'parent' => 'Parent Event',
 ),) );

 register_taxonomy('event-city',array (
   0 => 'events',
 ),array( 'hierarchical' => true, 'label' => 'Locations','show_ui' =>
 true,'query_var' => true,'rewrite' => array('slug' => ''),'singular_label'
 => 'Location') );
