Rick,
I have noticed that quite often I have about a two second delay when I click on that little button that it quickly oens the thread to a seemingly random spot then about 2 seconds later it goes to the post I am looking for. If i click somewhere on the page it seems to stop the transfer to the proper spot. Course it could be my imagination too.
GT,
Dan's suggestion is about all I have to offer up right now. I cant find any personal settings that would affect this behavior for showing the extra posts. Personally I like it because I dont always have time to read them all at once.
Chris
