I’m having the same problem with the updated, non-@-using version as well.
I’m running the plugin on two different sites, located at two different hosts. Flickr Manager works fine on one site, but not the other. I don’t know how the server setup would affect its performance. I can access all the plugin’s menus but can’t Insert Into Post.
I’ve switched to WP-Flickr for now, but I really miss Flickr Manager.
