Powerpoint quits after the last slide at presentation mode

[Guest]

I received a powerpoint file which starts in presentation mode and quits
powerpoint itself upon completion of the last slide.

How is this done ?
How can I edit the pages ?

You would've have received a PowerPoint Show (*.PPS) file.

How is this done ?

Save the presentation as PowerPoint Show or rename the presentation
extension from PPT to PPS.

How can I edit the pages ?

Open PowerPoint first and then select File | Open..., navigate to the PPS
file and select it to open it for editing.
