Running 64-bit F16 KDE. Lost my ability to shut the program down from the menu system. I've got to go into Konsole and type 'poweroff' to shut down the system. Can't say what may have caused this problem but am hoping for some quick fixes for the menu shutdown.
Any help appreciated,
BTW am anxiously awaiting the arrival of F17 KDE. If it's anything like F16 it'll be another winner.
