As I allready said, Q4OS's implementation of TDE is missing many elements that have to be installed afterwards, if you wish to have the usual services. Several elements of TDE settings are not installed in the default option. The latest I've discovered is elements of TDE settings present, but not working: TDE settings opens to an icon vue. There are Icons, but a click opens the *.desktop file in kedit. Example for "File Association": [Desktop Entry] Icon=filetypes Type=Application Exec=tdecmshell filetypes X-DocPath=kcontrol/filetypes/index.html Categories=Qt;TDE;X-TDE-settings-components; X-TDE-Library=filetypes X-TDE-ParentApp=kcontrol Name=File Associations Name[af]=Lêer Assosiasies Name[ar]=ارتباطات الملفات Name[az]=Fayl Əlaqələri Name[be]=Асацыяцыі файлаў (***) A workaround is to execute "tdecmshell filetypes" Obviously, the problem is a missing association, as if I copy the *.desktop file to my openSuSE system, everything works fine. But what is this association? x-desktop has no association in my settings. However, TDE/openSuSE opens *.desktop files correctly, as programs or as tdecmshell whatever... Where to look for information? Thierry
