Hi there,
As Jost Zetzsche writes in his latest Tool Box Newsletter, the dictionary and search engine LINGUEE (http://www.linguee.com/) has just released new language combinations (DE<>ES, DE<>FR, DE<>PT, ES<>FR, ES<>PT, and FR<>PT). Highly recommended. Searches within the Goldendict "Websites" option (e.g. Linguee DE>FR, "http://www.linguee.de/deutsch-franzoesisch?query=%GDWORD%&source=german") work just fine.
Kind regards.
