Hi. I don’t know why this happens, but when i insert a pendrive or CD, and go into the new devices plasmoid, and click my pendrive, for instance, there appears a window with 3 actions - open in Dolphin, import photos to DigiKam, and don’t do anything. Each time I choose Dolphin, it opens my pendrive in Konqueror! (The same thing happens with CDs)
This is simply a bug/feature of KDE4 at the moment. If you choose to make Konqueror your file manager, the message will still say Dophin because Dolphin is the default file manager but it will open in your preferred file manager.
If you really want to use Dolphin, make it your default file manager.
