I have been using the SkyDrive app for over a year now and I am always happy with it. Yesterday I was using the Word app and I realized Spell check was off, So when I went to turn it on, I found that on the right side of the page the was a little yellow box, saying "Spell Checking Unavailable" Do you have an explanation for this? Is it because it's a free app? is there a solution? do I need to purchase something? change settings? please advise...
