For example, I have four horizontal text boxes stacked on top of one another. So that the bottom of one is the top of the one beneath it. If I alter the size of the top box it now hits the center of the one below it. I would like the proceeding boxes to "shift" down automatically. Is that possible?
Why do you work with several frames (not boxes!)? Make one single text frame.
Or make anchored frames in succeeding paragraphs, each box in a single paragraph with auto leading.
Yes, text frames (not boxes)! MS Word still has a tight grasp on me!!! My doc is going to be an electronic form rather than a "regular" one. It is being designed to be used electronically (PDF) or print out. Thus the reason for multiple frames...
There is no reason to use multiple frames.
