F12 starting Gnote

[SternData]

When I upgraded to F12 from F11, I installed Gnote and removed Tomboy.
To get Gnote to start with Gnome, I added it to the session preferences
as "/usr/bin/gnote". Now, when I login, Gnote starts, displaying the
search window.  When I close the search window, Gnote exits entirely.
If I then restart it from Applications -> Accessories, it starts again
(properly) as a tray icon.

How do I get it to start as a tray icon with the session start?
