I've noticed lately that when I log on and click to view unread posts, it has been coming up with "No unread topics found since your last visit," despite there being a post made like only ten minutes beforehand. I see them all fine when I click to view ALL unread posts, but I shouldn't have to do that for a post only ten minutes old. Anyone else have this sort of problem lately?
I've been having that problem with the view new replies button... it won't show a reply that was made in the screenshot thread unless I put it though view unread posts first...
IIRC, it happens when the server clock catches after an hour or midnight, when it believes that it had been that long since you had been back.
