Sometimes doing it via the board doesn't always work if there is a corrupted cookie and part of the cookie stays. So when people usually have display issues on my site that no one else sees I tell them delete via browser not board and that fixes it.
This held true with a fix Rick post adding the new variable to the cookie to help fix the IE issue. The older cookie stayed since it wasn't the same as new one and conflicted. People were unable to log out among other things.
