Text Shadows In PowerPoint 2007 Beta 2

[Duddman]

I add shadows to text as follows:
1) Click on text box to select.
2) On HOME on the ribbon, I select "SHAPE EFFECTS" and go to SHADOW.
3) I select the shadow I want.

Here's the problem: the shadow shows up fine on the screen in the normal
view. When I actually run the slide show, the shadow effects aren't there.

What am I missing?

Thanks in advance for the assistance.
