"dot" key in numeric keyboard

Hi people, I'm from Brazil. Here we use a special keyboard, the ABNT-2 layout. SuSE has it in its keyboard vault, every key works like it should be. Almost all. In the right numeric keyboard below the plus key "+" we have a dot key ".", but this key doesn't work. It happens with Red Hat too. Seems like a problem with KDE translation or keyboard maps...Anyone knows how to fix it? I have to use the dot key that shares with the ">" one. Thanks for your time, Bruce
