Thanks for your post. I believe G00 turns the routing mode on and the drilling mode off. If possible, please submit a sample workspace file (*.wrk), to support@numericalinnovations.com and we will test exactly what is the cause; and perhaps make an option to suppress the output.
Note: To save a workspace file, load your design in FAB 3000 and then go to menu: File | Save Workspace...
