I am not a computer person. Bought this for my son. He built it, charged the battery and then turned on to start the process.
Please excuse my obvious ignorance that is about to show. He made it to the blue button part and the blue button would not work. So he restarted the Pi. That was when the tears and anger started. Now all the Pi does is boots, goes through the intro video and the piper screen shows. The mouse does nothing the pointer stays in the middle of the screen and clicking has no response. We have tried multiple other usb mice both universal and Mac/pc specific and nothing works.
