Applets not docking with system tray

Hi there…

I’ve been running OpenSuse 11 (Gnome) for a while now…

just now… I logged in and noticed something weird:
some applets that usually dock with the system tray…
are now opened in seperate windows on my desktop.

And I also noticed my title bars turning orangy from time to time.

Here’s the screen:

Any ideas on how to solve this?

Cheers,
Tom.
