GRUBonce is not working for me on 10.0

Hi everyone, GRUBonce will not automatically reboot the OS selected in the kdm (or from kde) menu. It just boots like a normal reboot was selected, showing the GRUB menu with the default choice selected. This was a feature I enjoyed using so that I could step away while waiting for a reboot. It worked fine on 9.3 for my same hardware, so I don't understand why it will not on 10.0. Any help will be appreciated. Thanks, Mike
