EdgardM,
So you got a pps as an attachment and double clicked it. Choose open and the
show has started, yes? Press Escape, that should end the show.
Instead double click the pps attachment and click the save button, put it in
a folder of your choice. Or right click the attachment, choose save as.
Now open it in PowerPoint, in PPT 2007 that would be by clicking on the
Office-button (upper left corner of the screen, looks like a giant pizza)
and choosing open. Browse to the folder with the pps and open it. Now look
for the loud speaker icon or look for the slide transition like Lucy and
myself tried to explain. You can zoom out using the zoom slider in the
bottom right corner of the PowerPoint screen.
If it is PowerPoint 2003, do the same thing, to open just click the Open
button on the default toolbar look for your pps and open it. You will find
the zoom on the default toolbar, click the listarrow next to the current
zoom percentage and choose 50% or even less.
For the slide transition look for the slide transition task pane on the
right of the screen. If there is no task pane, click View - task pane. In
the taskpane you will find a listarrow, click it and choose slide
transition. You will find the sound file (if present) next to the sound list
in the change transition section at the bottom.
