Problem with changepage and parcolumns about herries-press HOT 2 CLOSED

Sorry for the slow reply. I'm afraid this problem is caused by parcolumns and the way that it interacts with list environments; you'll also notice that even after the compilation occurs, the left margin of the parcolumns is incorrect even though adjustwidth attempted to change it.

To get the example compiling without the error, you can write in the preamble

\makeatletter
\g@addto@macro\endparcolumns{\global\@newlistfalse}
\makeatother

but as mentioned above the output will be wrong unless you only want to adjust the RHS margin.

Alternatively, you can also work around the problem by putting everything inside a minipage:

\begin{adjustwidth}{-5em}{5em}
\begin{minipage}{\linewidth}
  \begin{parcolumns}{2}
        \colchunk {\lipsum[8]}   
        \colchunk {\lipsum[9]}   
        \colplacechunks
        \colchunk {\lipsum[5]}   
        \colchunk {\lipsum[11]}   
        \colplacechunks
  \end{parcolumns}
  \end{minipage}
\end{adjustwidth}

(using the lipsum package) but in this case you then cannot break the text over pages, which is arguably even worse than the restriction above.

Sorry for the bad news; I'm afraid that there's nothing to be done, to the best of my knowledge. I suggest petitioning the author of parcolumns to add margin-adustment to his package, where it would be possible to some degree. (Since he has control over where the text chunks get placed on the page.)

Thank you,

In the end, using multicols was a good enough work-around for me, but it's good to know that the problem is fundamental to parcolumns rather than a bug at my end. Those hints will be useful for the future, though.

Best regards,

David.
