At times I get the message "Internet Explorer has stopped working and is trying to resolve the problem." I have to wait awhile until it gives me the option to "End Program", which I do, which simply resumes what I had been doing. In some cases it had deleted what I had entered. For years, this would happen on only on one site - Photobucket. Last week it happened on a new site I had just joined - Topix. Today it happened on my homepage (Comcast), while trying to read my email which I do everyday. What is happening? What can I do?
