Version: unspecified (using KDE 4.6.0) OS: Linux I see this on two different computers. When I log into KDE Num-Lock is enabled, yet as soon as I press SHIFT it is disabled. If I press shift while not being in KDE this does not happen. German keyboard layout. Reproducible: Always
Checked same problem on Fedora16. kde 4.7.4-2 kernel 3.2.7-1 PS only Kate editor is not affected
Apparently this is a feature. To disable, go to settings->input devices->keyboard->advanced and set misc compatibility options->shift with numeric keypad works as in MS Windows
Thanks to maciek gajewski. Was very annoying.
