I am using —> Tomato Firmware v1.28.7477.1 MIPSR2-Toastman-RT-Beta K26 USB VPN-NOCAT on a WNR3500l.
I went to delete a scheduled task from the Adminstration —> scheduler Custom 1 field.
When I delete everything from the command field and saved it, it re-apprears in the window when I go back to the scheduler menu.
I have found that you CAN overwrite it, but just deleting the commands for the field and saving it will not change anything. You MUST put something in the field for the change to be accepted.
You can turn the schedule on and off, so it is not like you are stuck with a scheduled item that you no longer need, but it is an annoying bug
