I'm creating a presentation for unsupervised viewing (like at a kiosk) and
want users to be able to navigate both forward and backward through the
presentation.  I have action buttons in place (no problem), and custom
animations set using triggers.  The animations work fine going forward
through the presentation, but if I move backward a slide the animation on the
previous slide is still in its final position (it has not reset).  Is there a
setting I can put in place that will reset the animation each time the slide
is loaded?  If I move backward 2 slides, then forward 1, the slide works
again but only if I arrive at the slide by moving forward.
