I'm working with a colleague who edited an Adobe PDF file by "deleting" the pages that she didn't want to have appear in a "preview" version and then she saved it with a different file name. Using Adobe PDF reader on a PC or Mac, the file appears as she intended. However, a person using Foxit reader was able to see the entire original contents of the file. Has anyone encountered this problem? What can be done to ensure this deleted information is NOT viewable in Foxit?
