Ugly (xemacs) font

[Joachim Reichel <joachim.reichel@gmx.de>]

Hi,

the menu font in my xemacs is really ugly (I've uploaded a screenshot to 
http://www.joachim-reichel.de/tmp/xemacs.png). I know how to set the fonts 
for the editor window, but not for the menu.

I do not notice font problems in other applications (KDE, Gnome, Mozilla, 
...). But xfontsel shows the same ugly font as default. I don't care about 
xfontsel, but it seems that the problem is not xemacs-related.

X packages: 4.3.0.dfsg.1-1
xfs-xtt:    1.4.1.xf430-5

I don't know where to start searching. The problem persists for some time 
now, so I don't know what change lead to it.
Any ideas?

Thanks in advance,
  Joachim
