Default settings for text boxes

I created a show by dropping many images in using the Photo Album function.
I'm adding notes using text boxes. For clarity, I formatted the first with
white background and a black border line. As I wanted all to be like that, I
clicked "default for new objects" before OK. Next text box, I had to start
over. It never "sticks." It seems to work for other shapes, but not text
boxes. How can I make a text box format stick so I don't have to format each
one? Why should a text box work differently from other AutoShapes, if the
default check box is available in the text box dialog box? I'm working in
PowerPoint 2002.
