Guillaume,
As installed in Mandrake 9 RC3, OpenOffice 1.0.1 will not run if invoked from the KDE menu items. When, as user, I ran the setup routine from /usr/lib/openoffice, the setup routine still did not copy the needed bash script files and subdirectories into the user's $Home/OpenOffice1.0.1 directory. I had to copy the bash script files over manually... George
