One fix is to change the contact-form-7.php file like this:
- On line 1162, inside the load_js function, change the wp_enqueue_script call to look like this:
wp_enqueue_script('contact-form-7', WPCF7_PLUGIN_URL . '/contact-form-7.js', array('jquery', 'jquery-form'));
Hope this helps somebody, and it would be great if it could be incorporated into the next official release.
