I've changed owner/permissions to zaurus.qpe/664 but the settings are still not saved. Does anyone know where these settings are stored and in what format?
Problem partially solved.
I discovered, after downloading and looking in the source code, that kismet_qt was looking for it's configuration file (kismet_qt.conf) in /etc/kismet but the package I installed from the ZUG feed puts it in /home/QtPalmtop/etc/kismet and calls it kismet_ui.conf.
Copying the conf file to /etc/kismet cured the problem but does it mean that the package was not intended for a C3100? If so what is the correct package?
Anyone out there running it on a C3100?
At least it is working now.
