This occurs randomly, sometimes works as normal, sometimes not.

When the ◆ Compose key is pressed, the Scroll Lock LED lights up until the composing is done. This is the normal behavior.

Other times, the LED doesn't light up, nor the other LEDs like Num Lock and Caps Lock, they get "stuck" somewhat to say. In this case, when I press the Caps Lock key, the corresponding LED don't light up (or don't turn off), the same with the Num Lock key, Scroll Lock key, and ◆ Compose key.

When this happens, I tried to unplug the keyboard, or restart WinCompose, but that doesn't solve the problem. I have to restart my PC to "reset" the LEDs of the keyboard.

I don't know if this is a problem of my keyboard specifically or not, but this happens only when WinCompose is running.

¿There's a possibility to "reset" the LEDs status of a keyboard from software? I mean, from WinCompose, a button to reset the LEDs, or in the Debug Window add messages about that.
