Hi Tony, | New versions of ferret has increased the default value of nlevels from | 10 to 30. Does anyone know if it is possible to permanently change it | back to 10? SET MODE NLEVELS only control the current session. Once | ferret is restarted, it rolls back to 30. I think you want to put your default settings in ~/.ferret . Ferret reads this file each time it starts. Regards, Ryo
