hi rigel I found the reason. KDE2 and Koffice can't work with the TrueType font in debian. :( ,When I set the kde2 font to "song ti" by hand, kde2 and koffice all work fine. In kword, when I change the font to "ar sungtil gb", it crash. I couldn't explain it. Gnome can use "ar sungitl gb" though xfs-xtt, and very stable. how about you? Could you use TrueType in KDE2? saka
