The iFinger engine is user-friendly and unobtrusive (it automatically docks to the title bar of the application that you’re using).
When activated, simply point your cursor over a word (either on or off-line), and the results from the reference material you’ve downloaded appear instantly in a pop-up box - the more products you have installed, the more iFinger will show you!

I find this program very useful for instant translating while for example writing a paper in another language. I recommend it to anybody and I hope GotD will finally end the 30-day trial problem I have with it. Thanks for your time!
