How can I move the pointer (the diagonal line) in a callout in PowerPoint 2003?
I want the pointer at the textbox to point to the middle, not the upper third.
Grab the yellow handles and move it. The yellow handles on shapes usually alter the geometry, eg the size and shape of an arrow head, or the radius of a rounded corner. Here it alters the position of the pointer line relative to the box.
Sorry Matthew, on PowerPoint 2003 you can't modify where the callout line meets the text box. It's exactly as you state on your blog,
The left diamond moves where the pointer points, and the right diamond moves the entire textbox.
That's it, sorry.
