While reading posts in the Latest | New | Unread area I was having difficulty clicking on the post. I noticed my cursor didn't change to a hand until I dropped it down a few posts. I ended up reading from bottom up. Then, when I got to the last unread post, it wasn't clickable; the arrow was just there. Until that is, I moved it slightly to the left. It seemed like there was a set width or margin that was clickable. Odd, I know, especially since I didn't sense this with the other posts.
Today/tonight I continued to have difficulty staying logged in or having the ability to read the Latest | New | Unread posts. I have gone back between "Home" and "Discussion Groups" from being logged in while on the "Home" page and not in any other area, including replying to a post ... when all I had to do was click the "Log In" button and my icon appeared and I was back to being logged in and was able to post my reply.
All this is intermittent and so far I can't pin it down. I use all browsers and they are all the most current, so I don't believe it is a browser issue.
Thank you, to one and all, who are assisting with all of these changes. Your time, energy, talent, patience, ... are greatly appreciated!
