I'm using Pages to take notes and save everything in pages, same for Numbers, and Keynote. I've also got documents that were created in MS Office and saved in those formats. Is there any way I can stop pages, keynote, numbers from asking to save the MS Office documents as iWork documents when there are NO changes made? It's annoying to open up a document to review something and be asked to save changes every time I close it without actually making any changes.
