I am sorry for my first letter , I spell wrong word "DURATION >60" ,
what i mean indeed is "DURATION <60" . this is the correct one :
	I installed hobbit and find it is excellent!
I was confused about the alert confiugre of "hobbit-alerts.cfg" , I
configured the DURATION <60 ,I assume it will appear in the "stop after
column " on the "info page", but I can't see it.  Maybe I am wrong about
the "stop after column" ,what does it mean ?
