Sorry if I wasn't clear but that's not what I was asking.

When I first come on to the board and hit the New Posts button, I'll get a few pages of threads returned who's titles are bolded and there's an icon to take me to the new unread posts.

But if I linger too long in a thread, or leave my computer, after a period of time when I return to the search results pages of new posts, the thread titles are no longer bolded, and the new post icons have all disappeared.

This behavior has lead me to believe there's a time limit in place where if there's no activity the software assumes you aren't there and deletes the search results for whatever reason - server response or memory reasons perhaps?

I was wondering how long this time period has been set for.

Thanks
