fabianx... many thanks for your help and support.
i tried to hdinstall knoppix 3.2 anso using wxt2 but i have the same cp error.
i guess i have to go back to knoppix 3.1

about antialiased fonts... i really like the way mozilla looks with them (dunno if it's because of xfree 4.3 or anything else) so i'll try to update my system once i get my old knoppinx 3.1 to work properly on hdd again
