This is happening only in search results. It works fine when I'm in my regular inbox. For instance, in my Inbox, if I see an email from Sarah, I click on that, then click "From" on the bar at the top, and all the emails get sorted by the sender, but the results jump to the email I highlighted from Sarah. When I try to do the same thing in search results, though, the list jumps to the beginning, and I have to scroll down to see all the emails from Sarah.

I was having other search issues, too, but I was able to fix those by reindexing Spotlight and by installing the most recent update, made available April 1, 2014. This is the last of my three complaints — all things that changed in the last month or so — and I just have no idea how to fix it. Please help.
