Hi, Elcam
This problem has existed for some time, It doesn't bother some computers, It has been an on-again, off-again problem for me.
This is a on-going development program, Use the right hand lower Layer/Object Porop... for entering your cut depth, each layer has
only one depth, if you need different depth on an item right click on it, assign it to a different layer.
Use the Set origin min button to set origin, it works fine you just cant move into the drawing.
Brian posted, It may be a Graphics Issue causing this, Fix in the works I hope.
Hope this Helps, Chip
