There is a gnome menu in kde main menu. The computer stop fuctioning while a mouse pointer trys to activate the gnome menu. I tried to remove all *.desktop files from /usr/share/gnome/apps, the gnome level menu then could be displayed in kde main menu. However, all submenu that contain *.desktop files will cause computer stop fuctioning. This mean, RedHat 6.1 for Alpha can not display Gnome .desktop menu item file in kde desktop. I need a cure.
This has been fixed a while ago - grab the kde and qt packages from Raw Hide (ftp://rawhide.redhat.com/)
