Allow one slide to 'overlay' the previous slide

[Guest]

I'd like a slide to display 'over top' of the previous slide, but I can't
seem to get the background on the second slide to go away. I know that I
can use animation and timing and all sorts of things to accomplish this
effect within a single slide, but in reality, I need a dozen or more slides
to build on each other, and I'm finding that too many items on the same slide
with animation effects is too complicated to maintain.

Is there a simple way to define a slide so the previous slide doesn't get
overwritten?

Try this technique: http://www.pptmagic.com/articles/3Dtransitions.htm

Simply lay a picture of the previous slide on the new slide and then add
your items for that slide on top. Repeat as needed.
