Proportional fonts in Kde?

[Edward J Young]

I updated my KDE packages, to 1.0and now GNU emacs19's fonts are
different, and very difficult to read. The video is now reverse video and
very difficult to read. 

I believe that they are now non
proportional fonts. So when running dired, for example, now the files
and permissions etc, don't line up. 

Is the problem the default font in KDE? 

If so how do you chang the default font in kde? 

Any other ideas? 

Thanx Ed
