Query: Be warned! Let them repair their own problems first!!

This product will screw up your Outlook and Powerpoint spell-check facilities. They know about it but won't offer a solution. If you proof documents with any regularity, this "upgrade" will deprive you of the facility. Also the Word documents are criminally incompatible with earlier versions (beware "docx"): if you email people your work, prepare to get messages telling you your docs can't be opened. What a dishonest, farcical way to proceed! Don't let them get away with it. DO NOT BUY UNTIL FIXED!
