I have noticed that in the past couple of weeks, when I call up the unread posts since my last visit, if I leave the site before opening all of them, (I frequently get interrupted), when I return to the site it says there are no unread posts since my last visit. I have not marked them as read, just saving them for later, but when I get back they have run away to cyberland. I don't think this used to happen unless you marked them as read, it just seems it is happening unassisted. Could someone check into this? Thanks!
I have seen this before. You should be able to see a spot on the right side that says "all unread topics" or something like that and it will bring up those topics that you have not read.
