Thank you Igor for attending to this situation. Since this has happened before with presentations made with a much earlier version, do I understand correctly that if I take the .pte file of each one and re "create" that this will produce the same file but in the latest version? I just want to check before trying. I realize that this will only help with my files and will not affect those that I saved which were created by other people. Again, thanks Kerry Boca Raton, FL
