 * Hi
 * This is probably not news: The window which si popped up from the WP editor and
   used to insert a shortcode into a post is broken in version 4.0. The window pops
   up (though the display is a bit off). But the “Insert” button does not work –
   the window just stays there staring at you.
 * The initial reason appear to be that the call to tinyMCE.execInstanceCommand 
   fails (albeit quietly) in tinymce/window.php.
 * The larger problem is that there have been big changes with tinmymce and its 
   having benn moved into the core of WP with version 4.0. There is quite a good
   write-up here: [https://make.wordpress.org/core/2014/01/18/tinymce-4-0-is-in-core/](https://make.wordpress.org/core/2014/01/18/tinymce-4-0-is-in-core/)
 * Cheers
    Tom
