After I finish reading a post, I click the back button my mouse and I get a message that says Internet Explorer cannot display the web page. (It strikes me as just a little funny that it is exactly like the message in the Google sponsor ad that appears after the first post.) If I keep clicking back, it will return to the message and eventually return to the list of posts. This problem just started a week or so ago and nothing has changed on my computer. I don't have this issue anywhere other than SMC.
