ok i traied all the free traduction webpages (ok... maybe not all but a lot of them including elmundo, reverso, yahoo, google, freetraduction, and others), all of them have the same problem, so... i don't know... mybe you can create a traduction button to translate the actual page or something like that.. don't know, yahoo offers a traduction bar for webpages, i dont know how it goes but maybe you could see how's it.
