LTRthanks undefined error

[freddawes]

I am attempted to compile a document with the biditufte-book document class and receive the following error.

`("C:\Program Files\MiKTeX 2.9\tex\xelatex\bidi\bidituftetitle.sty"))

! LaTeX Error: \LTRthanks undefined.`

A smaller MWE of the same class does not produce this error. The command \LTRthanks is not present within the document.

Did you load bidi explicitly? I get the error you state (as the second error) from

\documentclass{article}

\author{me}
\title{zzz}

\usepackage{xifthen}

%\usepackage{bidi}
\usepackage{bidituftetitle}


\begin{document}

\end{document}

The error goes if I uncomment bidi. that of course is not a very representative test though....
