problem is due to the ajax component. a workaround is to edit the /wp-include/script-loader.php and rem out the js scripts that is having a problem. around line 35
// $this->add( ‘ajaxcat’, ‘/wp-admin/cat-js.php’, array(‘listman’), ‘20070118’ );
// $this->add( ‘admin-categories’, ‘/wp-admin/categories.js’, array(‘listman’), ‘3684’ );
// $this->add( ‘admin-custom-fields’, ‘/wp-admin/custom-fields.js’, array(‘listman’), ‘3733’ );
