hi,
i notice that it hapen with me to and others, i notice that it is caused by konqueror 3.3, kdelibs4 and the base of kde3.3. here we cant install knoppix 3.2 or better, it is full unstable and not usable after hd-install, you will get a better stable knoppix with knoppix-3.1 and pat-get insall kde-3.2.2, kde-3.3 is nice but not usable here, i dont know if it will get better soon? i hope!
