I think I found the problem: If I start KDE apps like Kontact under Gnome - the keyboard focus gets lost in the systray where I have the KAlarm and KMail icons docked to systray.
If I quit KAlarm and KMail I can navigate through the panel with the keyboard without problems. -- Keyboard focus get lost in Gnome panel https://launchpad.net/bugs/34159 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
