I have TSO dataset profile set to automatic recovery on. After the system disconnects unexpectedly, when I log back on to TSO, I receive an error every time I go into edit with 'automatic recovery' in the title. The options are 1.) enter 2.) end 3.) defer 4.) cancel. No matter which option I choose, I am thrown back into the 'automatic recovery' screen the next time I go into edit on any dataset. How do I get the message to go away?
