I am using a single slide with a vertical page orientation in the middle of
another presentation in which the slides are in horizontal orientation.  I
created a hyperlink to the vertically orientated slide that works fine.  
However, when I click on the hyperlinked slide (which is in a second PPt
presentation), the next screen that flashes up is the "End of Show" page,
because of course, it is the end of the hyperlinked show.  I have to click
again to return to the initial presentation.  Is there a way to avoid having
the "End of Show" pane come up?  The presentation would be smoother without
it.
