Well from your post it is obvious this is not the way it behaved in the past, but I am not familiar with how it should work. I use the 24 hour search rather than the posts since last visit. We will look into it, first thing to figure out is exactly how it is supposed to act, IMO
, the number should stay the same, the entire time your on the site, when you leave, it should reset to 0 and start accumulating posts till you come back. Is that how it acted before?
