hey guys,
actually i've been using Longman Dictionary for a year and it's really wicked, i recommand you all guys to try it.
u can choose the American pronounciation or the British for the particular word, plus if you were browsing the internet, just point the mouse on any word and the programe will translate it in the programe window.
it's really wicked guys, i recommand you all to try it out.
best of luck
