I posted too soon, as I figured it out. In case anyone else is confused, from what I can tell threads not accessed since the upgrade go to the first post. But after the last post in the thread has been accessed, clicking on the thread title automatically takes you back to that post.
I am on a laptop running Windows 10 with Firefox browser. It's right above the solid (blue) bar at the top of the first post on the page and next to another button that says "Watch" - I tried to insert the screenshot but it won't let me so I had to put in a link instead, which will expire in a few days so check it out now.
Yes I know that. I as replying to @Japanfan's question from post #4.
Not sure what I said that made you think I didn't? Maybe that I couldn't paste my screen shot into the thread you thought I somehow was trying to use the "Watch" button to accomplish that???? No I used my right-click pop-up menu screenshot option and selected the area of the screen I wanted, which I then copied to the clipboard.
No, I'm sorry. Thanks for trying to be helpful. I was using a public thread like it was a private conversation, lol. I could have used the reply button for my post but since mine was right after the question I thought I would save some redundancy - and look what confusion that led to.
ETA: and for some reason I seldom remember there is the "@" option to help clarify - lesson learned (I hope).
