I started a thread here earlier an it dissapared, and then got a message that a mod had accidentally deleted it. So, woulc like to try again if the previous posters might be able to help. The users guide says toTAP on a word and I will be able to get a definition of the word. I have tried this in email, in an iBook, in a Kindle book and it does not work anywhere. I tred to, hold it and everything else, no joy. Somebody said to download a dictionary. I found several apps, and got one. Nce app, but still can't tap on a word and get result. Any other suggestions?
