This happens if you doubleclick on the "Operator"-Tab on the left side.
If you again doubleclick on the Operator -Tab it should be fine again
You can delete the folder ( system220.127.116.11.0 ) created under
admin is the current user logged in.
It will be created again during the next startup and everything will be reset. If you are scared to delete you can take backup of this folder
Thanks. Its working fine.
