Hi, Got KDE 4.5 and everything works OK, except getting a preview of files (eg jpg) on the desktop. It does not work when hovering over the file either. Both things work correctly in Dolphin.
Strangely enough, the following DOES work: - set Desktop containment to Desktop - create a folder view widget - configure the widget _not_ to use Desktop, but instead point to ~/Desktop. It looks like somehow the reference to Desktop is screwed up.
