I logged on last night for the first time after the upgrade and noticed some of the software glitches that I and other have posted about.
I also noticed that the forum shows many areas to contain unread topics, but when I click on the 'unread' "diamond" icon on the left edge of the forum, I get the message that there are NO unread topics.
I had thought that perhaps leaving the site, dumping cookies and a local machine restart would fix this, but did not.
I generally do not allow cookies ("NoScript"), but I do 'trust' this site and allow cookies from eHam.Com, but NOT from the Google conglomerate that tries to invade my machine when I visit the site. Even with these settings, the site has always worked very well for me.
As an aside: I appreciate the hard and tedious work that goes into a massive upgrade like this and I thank you for your efforts.
