PCLinuxOS Live USB Creator in an "in house" app, meaning that a member of our community, JohnBoy wrote it. It is not lili. If you're getting a double menu entry, you can remove one easily. Open /usr/share/applications in your file manager in superuser mode (i.e. as root user). Look for the 2 files labeled PCLinuxOS Live USB Creator and open one with your text editor. Look at its Exec= line. If it begins with kdesu, it is the file for the KDE desktop (menu). If it begins with gksu, it is for the other desktops. If your are using KDE, delete the other file. If you are not using KDE, delete the KDE file.
