Pondus ~
Thanks for the response. I selected the Last Known Good option when I rebooted, and it seems to have cleared up the problem. I am still not at all clear about what caused this problem. Does this indicate that there is a problem with some hardware (such as, for example, an internal modem is going bad), or was it a problem with something in the Microsoft Windows update? Just so you know, I am seriously deficient in the tech-world, so simple language and detailed explanations would help me immensely!
Thanks again,
Liza
