One of the apps I am working on is used for responding to customer requests. The text of the request is entered into a memo field as well as the response to the request. This is all then printed and sent to the customer. Spelling errors can be embarassing. Some customers are French speakig so I need the ability to check French as well as English, also there is industry dependent jargon so I need the ability to import a list of words into the dictionary as well as allow users to add on the fly.
