[dviout] dviout font rendering glitch on windows

[Beuthe, Thomas]

When I first installed TeXLive 2009 on my windows systems,
I also had the pfm mathtime and CM fonts installed native
on the system.
 
Everything worked well, except for dviout when I tested it
with the default cm fonts.  For example when I tried to render
the following document on screen as a sort of "hello world":
 
\documentclass{article}
\begin{document}
test test
\end{document}
 
the font appeared as some strange san-serif font that didn't
look anything like the cm fonts, even though dviout seemed
to be going through the right motions.
 
After a lot of testing and head scratching, I finally traced it
down to the natively installed CM fonts.  When I uninstalled them,
dviout rendered everything perfectly.
 
Does anyone have an idea how I can make dviout 
and the pfm installed CM fonts co-exist peacefully?
