I've edited a .pps file which was made with the 2003 version and saved also as compatible with PowerPoint 97-2003 but a friend of mine can't see the last version of the file. The original file can be seen by my computer friend.
What can I do to make the new version of the .pps file to be viewable on the computer of my friend? Any tips? Where/what else do I have to check/do?
