\documentclass{beamer}
\usepackage{soul,color}
\begin{document}
\begin{frame}
\hl{Hello World}
\end{frame}
\end{document}
I process this with pdflatex
and I do not see the expected highlight.
If I try to assign a color to overstrike same thing happens, as in
\setstcolor{red}
\st{Hello}
but \st{hello}
by itself does overstrike hello
in black when no color is set.
Why is that and what is a work-around? Many That I tried do not work with long text.
The Soul Package Documentation, footnote 5, says something about needing a Postscript driver.
I do not have a problem using soul
package outside of beamer
.
