Hi, I am studying for my PowerPoint cert test so I feel like I have to ask picky questions.

While the book I am using says the "Larger" and "Smaller" buttons in the Shape group size elements in a diagram proportionally, that is not what is happening in my test object. Clicking "Larger" causes the selected element in my pyramid to cover surrounding elements and clicking "Smaller" makes the element smaller, does not change the size of the other elements but does reduce text font size. Net effect...I am confused!
