I have a Samsung laptop and a Dell wireless bluetooth mouse. Up until right now, the mouse and the laptop worked fine. If they stopped communicating, I was able to restore that by using the Printers and Devices dialog in control panel.
But, my system crashed just now, and I got that blue screen that dumps physical memory or something and isn't really there long enough to read everything on it, let alone comprihend it, and now my mouse no longer works!
I can try and reinstall it, but it will vanish from the devices list almost immediately after being installed.... and it doesn't even work for those few seconds its there either.
