My installation of Dolphin seems to have taken a step backwards. Suddenly it has stopped auto-refreshing file views. Previously, if I downloaded or created a new file, it would automatically appear in the folder view opened in Dolphin. But now, for some unknown reason, I must manually refresh the view (F5) in order to see files. This is fairly annoying. I can't pinpoint what caused this change. I know that I did not change any settings in Dolphin. Is this change intentional through some software update, or a new bug? Thanks for any info.
