Need more info from you. What kind of object are you trying to use the set
autoshapes default with, and what are the exact steps you're using to do so?
Pretend I'm six years old and give us a step-by-step rundown.
What exactly are you trying to set, also? By that, I mean, are you trying to
set an auto line color, fill color, font face, font size, boldness,
justification, what?
