I've restarted calibre but it didn't help. I've been through Preferences but can't seem to find how to revert to the previous functionality: clicking on an author and just showing this author's books.
Edit: Sorry guys. Just found it under Preferences -> Searching -> Highlight Search results...
I guess the Find Duplicates plugin turned that option on.
you've most likely accidently pressed the second button to the right of the search 'go' button. press it again.
