Don’t know if its the website or my "upgrade" to Internet Explorer 8.
Normally I look at all latest posts since last visit. I read a message and then hit the Back button to go back to the list.
Now, when I do this, I dont get back to the list of latest ones, I get back to the list of latest ones BEFORE that, if that makes sense. Not these new ones but the ones that were new before them.
I’ll try using Firefox next time to see if it does it.
