Translators...need accurate and ability to reduce to fit page I am on?

I have used google and bing translators with mixed results...they both do not always translate every word. Other translators like yahoo...I cannot reduce to fit on same page as I am on. And then there are some that dissapear when you start typing which forces you to by hand, write the translation down on paper, then type. Does anybody know of an accurate translator (spanish) that I can reduce to fit side by side on page I am on?|||Sorry to tell you, but an accurate automatic transaltor doesn't exist. They all can only give you an idea of contents.
