2.0.0??
Do me a favor, Open Mach, go to general config, Check ignor tool change, ok, close Mach. Open Mach back up and check to see if it has changed in general config. If it has changed, go through it again only this time, before you close Mach, go to operator, click on set normal condition. I have no idea if that will help as it doesn't seem to be an issue on mine. I'm running version 2.0.059.
