今天，由於另一個問題，我更新了我的 TeX 發行版，從 2013 年 9 月左右的 TL13 發行版更新為 TL14 發行版（最新）。
更新後，忽略我的聲明flowfram之一，導致繼續使用早期聲明中模仿的三列佈局。這似乎只發生在我的參考書目中，使用.\newflowframeflowframnatbib
下面的程式碼：
\documentclass{article}
\usepackage[margin=2cm]{geometry}

\usepackage{lipsum}
\usepackage{kantlipsum}
\usepackage[bitstream-charter]{mathdesign}
\usepackage[square, numbers, sort]{natbib}

When considering the EoL phase, it's desirable to initially consider the shortest possible cycles of energy, namely reuse, and in closing consider the largest possible cycle, which would be recycling. Case studies in the UK have mapped the waste problem to comprise as much as 15 million discarded mobile phones each year\citep{website:fonebak}. Large scale reuse brings problems, however. A variety of problems arise when considering reuse of mobile phones, such as their low residual value, their small size or the complexity of channels through which they are distributed\citep{ends1997}. Furthermore, a case study reveals most private customers prefer to give mobile phones away\citep{ends2000}, making the previously mentioned legislation of EPR a considerably hard task to achieve. Currently, manufacturers, retails and mobile phone operators. Figures from Foneback\citep{website:fonebak} suggest this to be inadequate. One suggestion would be to promote horizontal collaboration between competitors\citep{canning2006}. Coercion among competitors puts forward a problem in the same fashion as that of renewable energy in the industry sector, namely the problem of managing and putting constraints on collective goods: to promote a change, everybody has to invest into renewable energy. So even though competitors would want to make a change, that change hits a threshhold. A consequence of such constraints is a hit to the economy as we know it now, which inherently forces a gradual change. One recommendation would be to develop a mathematical model, determining how steep this gradual change would have to be to compensate for the need for change currently. Removing a such barrier would be vital to success of reuse practices as we know them now.

對於一些書目條目，它實際上排版了參考書目：
@misc{website:fonebak,
title = {Fonebak - Facts},
url = {http://www.fonebak.com/},
note = {(accessed 28-9-2014)},
year = {2014}
}
@REPORT{ends1997,
author = {Environmental Data Services (ENDS)},
title = {Take back schemes launched for mobile phones},
issue = {264},
year = {1997},
month = {January}
}
@REPORT{ends2000,
author = {Environmental Data Services (ENDS)},
title = {Compliance scheme envisaged for mobile phone recycling},
issue = {304},
year = {2000},
month = {May}
}
@ARTICLE{canning2006,
author = {Louise Canning},

journal = {Journal of Business \& Industrial Marketing},
volume = {21},
issue = {5},
year = {2006},
pages = {320--329}
}
這兩個文件也可以透過以下連結取得：（壓縮包）
先前聲明的單列佈局流程框架（\newflowframe[3]{\textwidth}{\textheight}{0pt}{0pt}% or \newflowframe*[>2]{\textwidth}{\textheight}{0pt}{0pt}）（似乎）被忽略了。相反，它繼續排版三列佈局：
以前，輸出只是遵循我聲明的佈局，如下所示（來自主文檔 - 我顯然無法再模仿結果）：

這是錯誤修復的一個不必要的副作用，當清單環境跨越兩個不同寬度的流框架時，需要修復該問題。這是一個說明問題的最小範例：
\documentclass{article}
\usepackage{flowfram}
\usepackage{lipsum}
\twocolumn[1,2]
\onecolumn[>2]
\begin{document}
\lipsum[1-10]
\clearpage
\lipsum[1]
\begin{itemize}
\item \lipsum*[2]
\end{itemize}
\end{document}
該問題僅影響清單環境，並且由於參考書目位於這些環境之一，因此這就是為什麼文件中出現問題的原因。您可以透過\linewidth\columnwidth在清單環境之前插入來修復它。例如：
\documentclass{article}
\usepackage{flowfram}
\usepackage{lipsum}
\twocolumn[1,2]
\onecolumn[>2]
\begin{document}
\lipsum[1-10]
\clearpage
\lipsum[1]
\linewidth\columnwidth
\begin{itemize}
\item \lipsum*[2]
\end{itemize}
\end{document}
對於您的範例文檔，放在\linewidth\columnwidth前面\bibliography。
編輯：我已修復此錯誤並將 1.17 版本上傳到 CTAN。可能需要幾天才能進入發行版。
