Unhome on Estop

I am trying to get my mill to unhome all the axis after an Estop . If I add VOLATILE_HOME = 1 in the INI file for each axis this works if the machine is not moving , but I get the error message in axis "cannot unhome while moving , joint 1,2 or 3" depending on which is moving.
I would like this to work to force me to rehome after an Estop when position could be lost.
Am I missing something simple ?
Thanks Mike

Please ignore the above . Have tried again and only get these warning messages when in manual control. When in MDI or running a program everything works fine.Sorry to have wasted anyones time Mike
