Excuse my lack of clarity. This is in Word 08.

Clicking once on a box selects the whole group, as shown above. A double-click lets me edit the text but not change box size. A double-click in the 07 for Windows version I used to today let me change box size as well as text.

I just can't for the life of me figure out how to get those 8 little blue dots around an individual box. But I thank you guys for trying to help.
