It would be useful to change the Due date on a ticket without having to change the status to open.
Just discovered this limitation now. Yes, please remove it.
I see this is still an issue. Another vote here to remove the requirement than the ticket status be OPEN before the due date can be changed. Silly.
Agreed. Having the same problem here. Need this enabled.
Agree, just ran into this problem. Seems unneccesary hurdle from enduser perspective.
