I'm suspecting that Magic Fields is not working together with WPML with the latest release of WP. In the WPML menu setting "Translation Synchronization" I get a message saying "WPML doesn't know how to translate this plugin." about MF. The problem comes to when I try and translate a post that uses custom fields - the new post decides to use the Uncategorized category (and not inherit the translated one) and I lose all the settings, hence no data is duplicated from the original post (which can be quite discomfortable if you have about 10 custom fields where one is a gallery).
