When selecting "show unread posts since last visit" I normally get some threads with "New". But if I go into subsections there will often be new threads not shown in that filter.  Any ideas pls ?

cant say for sure since how things work will vary from software to software and depend on admin setting choices, but my hunch is that the reason is, new posts show up in unread posts, and threads that have had posts edited by their posters show up as new in subsections only...

Pugchief's suggestion seems to work. Thanks.
