Hey Logitech, with the MX keys I got some wired bug for as long as I use this keyboard. Sometimes,when u use the Volume keys in the top of the keyboard, the fuction is stuck and it keep constly raising or lowering the volume. The only way to make it stop is to turn the keys off. I wonder if u can fix that bug VIA the new logitech firmware. I believe it happens when I waking the keyboard from sleep-mode by pressing the volume keys.

sorry in advance for my poor english. and big thanks for ur excellent hardware
