After trying the solutions suggested I still had problems (eg, no menus when I right-clicked on the desktop), so... 1) I backed up that users home directory. 2) I used userdel to remove them from the system. 3) I then deleted their home directory. 4) Next, I used adduser to put them back as a new user. 5) finally, I restored the essential files to their new home directory. They still had some reconfiguring to do to get things back the way they liked, but at least all works now. Trevor
