New install of OpenSuse 64-bit. I've stumbled around blindly and seem to have installed Dropbox with dropbox-lnx.x86_64-1.1.24.tar.gz. It apparently worked because I was able to enter my Dropboxlog-on details successfully.
I have no idea what to do next. There's no indication of any synchronisation in Dolphin.
Please bear in mind that I'm a complete KDE newbie.
