If I turn on my computer and use keyboard for normal computer functions like emails,surfing the net, etc.. I have no problem. The problem starts when I open MACH3 and turn on the power to the control box. It asks me to hit the reset button, which I do, but I get the status message: initializing macro called on reset and my computer just stops working. I have to literally reset my computer to get the keyboard to work again. I am not sure why Mach3 triggers my keyboard to stop. Could it be some sort of energy surge when I turn on the control box?
