My zypper dissapeared from the tray this morning. There was an area
wide outage of the connection from my ISP for a couple of hours. When
it came back online,
I noticed that there was no zypper symbol in the tray as it usually
is.
Even re-booting did not bring it back. it still shows in user/bin/
zypper.

How do I restore it to its usual place in the tray?

Thanks,
