[OzTeX] \usepackage{color}

[Larry Susanka]

Hello;

I have a forty page manuscript with 20 paragraphs temporarily typeset 
in blue as a rewrite-reminder. I have been using the color package 
and the tag

\textcolor{blue}{ colored paragraph here. }

I have been getting (sometimes) a warning from OzTeX:

Stack underflow for color \specials!

as I scroll to a page with color text, and some of the blue-tagged 
text on that page shows up black.

This is not a big deal, but I am curious. Why does it do this? Can I 
modify something so that does not happen?

Regards,
Larry Susanka
