Do you have your browser configured to empty your cookies when exiting? They are required for this feature to work.
Yes, I do have the browser configured to empty cookies upon exiting. I have always had that setting configured, so I'm assuming something happened to AC Forums on 12/19 to no longer have that feature working with this particular cookie setting?
One other question. If I change my browser settings on all 4 computers I regularly use to keep cookies upon exiting the browser, how will this work when changing computers? Previous to 12/19, even with cookies being deleted upon exiting, I could leave work in the evening and come home, and when I logged on to my home computer and went to AC Forums, the "see first new post" would work perfectly. Now that this feature is tied to cookies on a particular computer, am I correct in assuming that each computer I go to AC on will have its own idea on what my "first new post" would be?
