Morning all.
Richard, as you know it is easy to send out a PPS file instead of a PPT. The PPS is a self contained and anyone can run it even without PowerPoint. The PPT, yep it needs PowerPoint installed on the computer to run. And why in the world not just send a PDF. Everyone can read a PDF.
Oh well, as a friend of mine says. "It's not my farm, not my pig" which sums it up perfect. Not my problem. Good luck!
