When I turn on the lightning of my keyboard, it automatically turns back of after a second.

I've set Keyboard LED to disabled in WinCompose options.

In the logs, it is seen that I press down the ScrollLock key, which is the key to turn up the leds, and when I release it. But when the LEDs automatically turn of again, no events are shown.
Note, I'm only speaking about the LEDs behind my keys, the NumLock LED stays on.

The cause is probably related to #321
