I have a MX-900 that I have programmed and has worked with no problems until recently. It has started freezing and doesn't respond to button presses. I have removed the batteries and replaced, it seems fine for a few seconds then freezes again. I have reset to factory and reprogrammed and it still freezes. I have replaced the batteries thinking it was my Sanyo Eneloop batteries but seems no different. The one thing that is weird is if I remove the batteries and plug the usb into my computer it powers up and doesn't freeze? One thing to note is that when it does freeze the LCD screen remains on. I was wondering if it could be the batteries losing connection in the holder?

Thanks
Steve
