Version: (using KDE 4.1.3) OS: Linux Installed from: Ubuntu Packages 1. Open a single view of a directory. 2. Split left/right and navigate to a new directory in the right hand pane. 3. Switch to the left pane. 4. Split top/bottom One expects the same behaviour as in KDE3: three visible panes; the left one split top/bottom and the right hand one unsplit. In KDE4, the right hand pane disappears and has to be dragged back into view order to see all three panes.
