Spindle CCW button shows up - despite not connected

Thanks - so the good news is that I didn't mess up the configuration. I'll double check that the unwanted button doesn't actually do anything when I get the PC connected to the mill.

Looks like this used to work 'as advertised' - the PC is replacing an underpowered one which could only cope with EMC 2.3 - just checked today before swapping PCs, that old one only showed the spindle CW button. I'll have to put a post-it on the screen to hide the CCW button....
