Re: More Page Break Problems

My sympathies. Pagebreaking is a HUGE weakness for Mathematica. I've
probably spent hundreds of hours struggling to get decent page breaks.
The primary reason for MY woes is that line and page breaks depend on
whether cell brackets are shown. So if you're working with cell
brackets on and printing with cell brackets off, page breaks will not
be where you expect. So the only way to get reliable page breaks on
screen is to work with cell brackets off, which is a royal pain in the
%&$#.

As result of your previous post about inserting page breaks without
going to the Option Inspector, I've made my life a lot easier by
creating a little palette that lets me easily turn cell brackets and
page breaks on and off, insert a page break cell (thanks, Rolf Mertig)
and ``refresh" the window. The notebook is attached. I hope it will be
of help.

                    Mathematica-Compatible Notebook

This notebook can be used on any computer system with Mathematica 3.0,
MathReader 3.0, or any compatible application. The data for the
notebook  starts with the line of stars above.

To get the notebook into a Mathematica-compatible application, do one of
the following:

* Save the data starting with the line of stars above into a file
  with a name ending in .nb, then open the file inside the application;

* Copy the data starting with the line of stars above to the
  clipboard, then use the Paste menu command inside the application.

Data for notebooks contains only printable 7-bit ASCII and can be sent
directly in email or through ftp in text mode.  Newlines can be CR, LF
or CRLF (Unix, Macintosh or MS-DOS style).

NOTE: If you modify the data for this notebook not in a Mathematica-
compatible application, you must delete the line below containing the 
word CacheID, otherwise Mathematica-compatible applications may try to 
use invalid cache data.

For more information on notebooks and Mathematica-compatible 
applications, contact Wolfram Research:

  phone: +1-217-398-0700 (U.S.)

Notebook reader applications are available free of charge from  Wolfram
Research.
