It may be too soon to declare victory; but we haven’t had any issues with the computer since the last device driver configuration change I made on Sunday. So, perhaps, the problem is finally fixed. Even if it still hangs sometime in the future, it’s definitely happening a lot less than it was previously. And, now that its not such an annoyance, I’m not spending as much time searching for a solution. Computers are mostly great inventions. But, sometimes, they can be a gigantic nuisance.
