Try selecting just the last slide and in the slide transition pane increase
the auto transition time. Do not click "Apply to all" just close the pane.
See if that works
An alternative way which I prefer is to have an animation OFF SCREEN set to
very slow (5 secs) This can be eg a rectangle with a fade entrance.
