How do I resize Data Labels in Powerpoint?

[Guest]

In Powerpoint, I can't seem to re-shape the data labels text boxes in my pie
chart. I can change the font and allignment of the text within the text box.
But, if the text defaults onto two or three lines, I cannot stretch the text
box out to get the text to stay on one line. Normally, you can pull on the
the little handles on the text box. Is there a trick to this that I don't
know about?

Data labels cannot be adjusted. It's frustrating, I know. I usually resort
to using manual textboxes on the slide or chart.
