Version: (using KDE 4.4.0) OS: Linux Installed from: openSUSE RPMs To reproduce: 1. Open two PDF-files with okular 2. On the first file select the view mode "single page" 3. On the other file select the view mode "facing pages" 4. End the KDE session 5. Log in again and you will see both documents are in the facing pages mode.
Currently the view mode is global, so in your case there's no guarantee of which is the final configuration being saved. This will be solved automatically when bug #200183 is implemented (this is another consequence of the lack of it). *** This bug has been marked as a duplicate of bug 200183 ***
