I use the following options to the preview version of texpower
\usepackage[sans,coloremph,colorhighlight,lightbackground]{texpower}
Is it possible to change the pagecolor for the whole document without
modifying tpcolors.cfg? If I put a \pagecolor{..} just before or after
the \begin{document}, it has no effect. If I put it in each slide
environment, it works, but it's "overkill".
Thanks
Stefan
