I have a number of folders for correspondence from different people and filters set up to direct incoming emails, which all works well. When I click on a folder to see those emails, the view always automatically scrolls down to the most recent. The problem is that for one particular folder, this doesn't happen - instead it scrolls to a random old email and I then have to scroll down to see the latest. Is this a known problem and how could I fix it?

I have tried Folder->Properties->Repair Folder but ir doesn't help.
