Thanks for the suggestions, but the notification area is still messed
up.

I restarted the panel, but it didn't change anything. Then I
removed the notification area applet and removed it from the panel.
Then I looked for the configuration file, renamed it, and logged out and
back in, and then added the notification area applet back to the panel
but still no change. 

The only thing is that my file was not systay-4.rc, but rather
systray-13213260791.rc. I appended .old to it, but when I added the
notification area applet back to the panel no new systray-X.rc file was
created. The datestamp on the systray file was back in November, 2011,
when I first started using Xfce.

Do you know who the developer(s) of the notification area applet are
and how to find them or their website?
