Page Layout ⇒ Page breaks using mdframed

[Zetison]

I use mdframed to write mathematical proofs in a box. Sometimes these proofs spans over several pages. This is fine as long as the frame is not cut in such a way that only a small partion of the box is left on a page.

So in the following code, the first frame is accepted while the other one is not.

Code: Select all

\documentclass[10pt,a4paper, makeidx]{report}
\usepackage[utf8]{inputenc}	
\usepackage{amsmath, amsfonts, amssymb}	%Enable mathematical expressions
\usepackage{mdframed}	%Package for making environments for proofs and example (using minipage)
\usepackage[margin=1.2in]{geometry}	%Defining the margins
\usepackage{parskip}	%Making a new line instead of indentation (for paragraphs)
\usepackage{blindtext}

%Defining some colors
\definecolor{examplesBackground}{RGB}{220,226.5,237}	%Background color for example environment
\definecolor{examplesHeaderLine}{RGB}{122,150,191}		%Color of header line in examples environment

%Environment for examples
\newmdenv[topline=false, bottomline=false, leftline=false, rightline=false,backgroundcolor=examplesBackground, frametitle={\tiny\hspace{2cm}}, frametitlebackgroundcolor=examplesHeaderLine, frametitleaboveskip=-1pt]{examples}
\begin{document}
	\blindtext\blindtext\blindtext\blindtext\blindtext	
	\begin{examples}
		\blindtext\blindtext\blindtext
	\end{examples}
	\blindtext\blindtext
	\begin{examples}
		\blindtext
		\begin{align}
			F = ma\\
			F = ma\\
			F = ma
		\end{align}
		\blindtext		
	\end{examples}	
\end{document}

This code looks fine for me both on WriteLaTeX (the link is above the code) where the second frame isn't split at all and on my system (up to date TL 2013) where the second split looks as follows:

Right. The problem is that the second split is not preferable...

This is very vague... What exactly don't you like about it? Looks fine to me.

It is a "widows and orphans"-problem. Either more text must be splitted into the next page, or there can be no splits on that frame.

I would agree if it were only one line (i.e a real widowed line) or even only a part of the coloured frame without text. Still:can't you be more concrete? How many lines would be acceptable?

Let's say I want no less than 5 lines on the new page, is this obtainable.
