Found this: Unread posts | Classic Camp Stoves Dim memory of it happening to me many years back and that it was subscription lapse.
There may be a logical reason for this, like you cannot compare an unread post count with the number of unread threads. When I opened this one thread, I found 9 unread posts. My unread post count dropped by 9.
Yes, if you open a thread, the unread posts within that thread will become 'read', but it really couldn't be otherwise: the confuser only knows if you've opened it, not whether you actually read it.
Thanks guys for all the feedback. This is only a recent thing. If I start off with 50 unread posts the counter drops correctly with each thread opened. I tend to open posts at random so in order not to lose my bearings I click on the unread posts button at the top of the forum to reset the count and it normally tallies but once it's down to only a few unread posts and I open the last thread the red 1 or 2 changes to a black 0 and by the time I've scrolled to the bottom of the posting and back up the counter at the top has gone back to a red number and I reset it again and there are 1 or more threads appearing that I know I have already looked at with no additional posts to be seen. @snwcmpr I'm using chrome as my browser @Ed Winskill It doesn't look my subscription has lapsed. I have seen that before though, because you loose access to some of the forums while your subscription is in limbo. @Dean mine has always done the same but once I reach the point of clearing the backlog I get the strange behaviour that I've noted here. Thanks to the Moderator that moved this thread into the correct forum. I knew this one existed but could not find it earlier BC (before coffee). Regards John
another example from this morning; There were 3 threads left after resetting unread posts, I looked at two of them and the counter jumped to 0 despite there being one left to read. Regards John
