I think this is a bug in the release posted on the openSUSE repositories, but not sure if any one else experiences this. I am running AMD X86_64 implementation with an NVidia Quadro FX1400 graphics board. I am using the most recent versions of KDE 4.2 from the openSUSE repositories.
When trying to select files within Dolphin using the icon display mode, holding the Shift key and clicking on a file name after selecting another file, does not select the range in between, all it does is select the new file name, like the Control key would.
