KDE kbd repeat won't stay on

I noticed that my keyboard wasn't repeating when I held down a key, so I went into the KDE Control Center and turned on the repetition. All was well until I rebooted. When I got back, the repetition had been turned off again (and the KDE CC indicated it was disabled). What do I need to do to cause KDE to preserve the setting as it should? Or is this just a bug that I can't do anything about? Paul
