[pdftex] Red-colored number? (pdfscreen & lastpage)

[Troy Goodson]

I noticed that when I use pdfscreen and lastpage together, I get a 
red-colored number.  I see the red number in both Preview and Adobe 
Acrobat Reader 5.1
If I take pdfscreen out, the number turns black, as I expected it to be 
in the first place.  Any ideas?

% this gives me the red number
\documentclass{article}
\usepackage[screen,nopanel]{pdfscreen}
\usepackage{lastpage}
\begin{document}
\begin{slide}
      \pageref{LastPage}
\end{slide}
\end{document}

% this gives me the black number
\documentclass{article}
\usepackage{lastpage}
\begin{document}
      \pageref{LastPage}
\end{document}
