# LyX headers and footers don't span page [closed]

I'm creating a document using LyX with various packages in the preamble. I'm setting different fonts, setting colours and I have `multicols` working. The problem is that for some reason, the headers and footers only span about three quarters of the page (or around the centre point of the second column).

Is there anything in multicols which might be causing this?

My mimimised preamble is below. It does it without any text. I'm sure that one of those parameters is mucking it up, but I'm not sure which one.

``````\usepackage{multicol}
\setlength{\intextsep}{0cm plus1cm minus1cm}
\setlength{\textwidth}{39pc}
\setlength{\textheight}{54pc}
\setlength{\parindent}{1em}
\setlength{\parskip}{0pt plus 1pt}
\setlength{\oddsidemargin}{0pc}
\setlength{\marginparwidth}{0pc}
\setlength{\topmargin}{-2.5pc}
As a follow up to Alexis' comment: To create a MWE in LyX, remove as much as you can from the document and from the LaTeX preamble (if you have anything there) without removing the problem. Then export the LaTeX source, open the `.tex` file, and edit your post to include all the text in it. You could alternatively open the `.lyx` file in a text editor, and copy all of that to your question. –  Torbjørn T. Dec 11 '13 at 13:16
(Old question I know. I wasn't notified of your comment as you didn't write `@TorbjørnT.` -- the `@` enables notifications, just noticed it again.) Is this still a problem? I'm unable to reproduce the problem with the code you posted, so you need to produce a complete example if you'd still like to get an answer. If you've figured it out yourself, please post an answer yourself. –  Torbjørn T. Mar 13 '14 at 12:59
