It is not related to this problem, but you are right in that. Cookies are kept on your machine, but last login is kept on the server. Cookies are used to keep track of what topics/forums are read in the current session (to make them white). When you start a new session, orange status shows the new posts since last login. So topic-read tracking cookies don't have to reside on server side.
Thanks, so when I log out and back in, it still did not correct it (I tried it an hour or two ago). But I did not close browser.
Now, Next time I will close browser and see if corected when occurs next.
Does that mean that sessions over 15 min's are susceptable to this bug, or that it only refreshes the read/not read icons every 15 min's?
I have similar issues, but I read the forums from different machines around the house. I also often have 2 or more tabs open, each displaying a different topic. I just accept things will go a little pear shaped when you browse in such a manner.
OK Steve, FYI.
This has happened twice more since last post, and I closed browser and reopened without logging out, using auto-login and icons were restored to correct status.
Hope this helps if you are interested in the feedback.
Look at last visit time (near the top left). If it looks reasonable, then you are ok. The number should stay constant for the duration of a session (about one hour //not 15 minutes). A session would elapse if pages are not visited for one hour.
