Hi FariJo,
Over the past three weeks, even though I've used my mouse extensively, I've only had the problem happen once, to my amazement. Before Windows 10, it used to happen about every ten or fifteen minutes.
It seems that none of us is any closer to identifying the real cause. We still don't know if it's a hardware problem, a firmware problem, or a driver problem--or some combination of these. This thread is turning into a mystery novel. :)
Good Luck,
Steve
