Screen Font

[Riccardo]

I'm using LyX to write my own thesis, but it happened an odd very bother
situation: the
screen font are suddendly become raw, more  rought. When i using the
option : OPTION -> SCREEN FONT to select a different font don't happen
nothing. I'm
using a RedHat 6.0 dist. that have a bug with Netscape which is possible

to solve writing this:

chkfontpath --add /usr/X11R6/lib/X11/fonts/75dpi

Anyone can help me?
Thanks
Riccardo
