Does anyone know the answer to this question? I have had the offer of MS Office 2007 from my daughter. However, I have read somewhere but cannot remember where about incompatibility issues with previous Office versions - never been an issue before. What I read or think I read concerned "Word". The jist of the article said that if a document is created in Word 2007 then previous versions e.g. Word 2003 cannot open the document without downloading a special application - is this true? The reason I ask is that I often work from home then make amendments to documents at work or send Word documents to other colleagues. If they cannot open them then there seems little point as company policy means all PC's are locked out of downloading and installing applications, from whatever source.
