Hi to all..

Would like to know please if anyone experienced what I am. When I run Mach3 and toolpath or even just a spindle run Mach 3 goes bananas. I can see applications starting up on their own, such as the calculator, or mail box, and can see that the + and arrow keys are activating themselves like as being pressed from the keyboard. This happens when my cnc is on. In offline wont happen.
What is the mysterious thing???!!
