Good that it works for you.

In any case, since my environment is fairly different from a standard knoppix now, I have removed both 'hal', 'gvfs' from my system, as they are not needed by the newer pcmanfm. I also have removed /etc/udev/knoppix-post.rules from my system, as it seems to intervene than to help.

I guess that's what Linux is all about. There are just too many ways to accomplish something. Happy knoppix-ing.
