What ECU version are you running, and how is your computer connected to the MS - direct serial cable, external USB adapter, or a USB adapter built into the MS?

I recall something here that stated if you leave a usb->serial dongle (or was it a serial cable??) connected to the MS - you can get hangs.... when you remove the laptop are you removing the serial plug or letting the cable work as a good antenna for noise ??
