> Would you send me your patch, please? Jack, Looking carefully at Coriander, if absolute_capable is TRUE then it will DISPLAY absolute values (like real valued shutter speed instead of integers than mean little). But it will only allow the user to EDIT (thus calling set_absolute_value) is abs_control is also TRUE. On the XCD cameras, abs_control is FALSE. A very simple fix makes this work correctly.
