I checked my cookies and don't see any cookies with davidsprague in the name. I am very reluctant to delete all my cookies as they are pretty useful on a lot of sites. I have over 1500 cookies from various sources on my laptop. Any other ideas to get back the flagging of only NEW messages? The volume of posts has grown so great that even looking at only two days worth of messages (as I do), it takes a long time to page through these to see if there's anything new on threads that are of interest.

Any chance of getting a program that will highlight the offending cookies so they can be found and deleted? Using the "search programs and files" feature on the Start page of Windows 7 doesn't seem to find windows... maybe they are not regular files. Hidden maybe?
