OK, that's freaky...
When I delete it now and restart the whole panel, it's gone... It wasn't
necessary to apply Updates. But I'm going to update now and hope, that it's
done with this.
Thank You :)

At the right side of the screen is a new panel which seems to be useless. I can
delete it, but when I kill and restart the whole panel, it's there again. A
screenshot may help
