Many thanks forthe reply! When I tried this from the root, I got:
# ld_libray_path=/opt/lib nano
nano: No such file or directory
… which is the problem I got before with nano not being able to be used.
On another track (perhaps related?) when I try to edit the file from within Windows, I can open the file, but not save it back again. I get a refused permission type message. Do I have to go through changing permissions for files like .playlist and .conf that I may want to edit?
