The 'Add Gravity Forms Directory' option does not work in the post editor, when attempting to insert a directory in a page/post.
In addition, the 'Add Gravity Form' and even the standard 'Add Media' do not work. http://screencast.com/t/lxBuadPGCNCL
If I turn off the Directory plugin, the Add Gravity Form and Add Media work fine again.
Using version 3.3 of the plugin.
