I decided to downgrade to KDE 3.2 Mandrake 10.0 Official. The dead keys bug was present not only in LyX and Kword but in other qt apps like Scribus. I found no comments about this possible bug on KDE's site.
158 rpm to remove and almost as much to reinstall... But everything went fine and the dead key bug is out. LyX qt needs KDE even if I mainly use WindowMaker... Raymond -- �dit� et transmis avec des logiciels libres sous Linux !
