How can I make the docklet work under the GNOME desktop environment?
1) Make sure that you have added a notification area / tray to your taskbar. In GNOME 2.6, right-click on the task bar and do “Add to the panel > Tools > Notification Area” (in German: ,,Zum Panel hinzufügen > Werkzeuge > Benachrichtigungsfeld”). Without this, the Psi docklet will show as a small window on the desktop, but you can’t drag it into the taskbar. 2) Enable the Psi docklet feature. 3) Close Psi and start it again. In my case, the docklet shows as a separate icon window as soon as you enable the docklet function, but when you close Psi and open it again, all works fine.
