Sorry for the delayed response. My newsgroup checking is sporadic over
the weekend. The easiest thing to do is to hide and show objects. A
simple VBA command like:
ActivePresentation.SlideShowWindow.View.Slide.Shapes(5).Visible = False
will hide the fifth shape on the current slide.
You can check out some complete examples that use this method to hide and
show objects at my Web site:

Examples 6-6 and 6-8 do this kind of thing. You are welcome to download
these examples and play with them. If you have never done any VBA, you
might want to start with the "Programming PowerPoint" section of thePPT
FAQ:

Otherwise, someone here might have the time to whip up a quick example
(sorry, that is not me this week), but you don't need too much VBA to get
this to work, so it might be good for you to try to learn it yourself.
