Not sure if this is related, but in visiting the forum today I was asked to log in. When I did, none of the threads I've followed are indicated as having been read. It's like I'm visiting for the first time. All my PMs are intact but everything else is new. BTW, this happened on two of my machines so I'm thinking it's a forum issue rather than a local one. Might cookie history have been wiped by the ugrade?
Chris, you probably already know but I have found in the "What's New" view that the small blue arrow on the left that is to take you to the first undread thread actually brings you to the start of each thread. Once on the thread the top central view first unread button works fine. When in the "What's New" view the blue arrow on the right next to the member who posted last still works and takes you to that last post. Thanks for the continued upgrade work and effort to the site.
