Hello netters,

I am having difficulty in getting the \LaTeX\ logo in the \title command
in my LaTeX document.

The commands that I am using are:   

\document[xypic,11pt,twocolumn] {article}

\begin{document}
\title{\bf Typesetting Diagrams with \protect\XY-pic\ in \LaTeX\ and \TeX\ }

 Lots of stuff here.

\end{document}

In this document, I am using the \XY-pic\ macro package developed by
Kristoffer H. Rose of the University of Copenhagen, Denmark.  However, I 
guess that, that shouldn't make a difference to the \LaTeX\ logo.

My difficulty here, is that all the letters in the title including the 
\TeX\ logo are in bold font, except for \LaTeX\.  I tried \protect -ing
\LaTeX\, but that didn't help, nor did removing the twocolumn option
in \documentstyle.

A few months ago, Anita Hoover from University of Delaware, U.S. had
posed a question in reference to creating a symbol in the \title command
that did not appear in bold font.  Later, she pointed that there was some
bug in lfonts.tex and had corrected the bug. 

Does my problem have anything to do with lfonts.tex?

Can anybody take a look at my problem?  Any help will be much appreciated.

Thanks
