I was in a hurry to finish up a report that I needed to have done the next day. Just as I was adding my final comments to the paper, my computer started acting up. I had heard that some people were having trouble with Windows 7 locking, however, I never experienced it. This was the first time that this had ever happened to me, and I was concerned that it would be an ongoing problem. Although it was only a temporary problem for me, as it worked fine once I rebooted the computer, I still am concerned for the reason behind the problem.
