Is there something in System Settings that will stop the rotating blue circle in the middle of the screen without having to unplug the device? Currently, I'm forced to do an ALT/CTRL/DEL or unplug the device to fix the problem. If I have recently done a factory reset, the blue circle problem will resolve itself in 5 seconds. I've deleted cache/cookies/history, but that doesn't stop the problem from re-occurring. Any help would be appreciated.
