[strike]The '6' just died on my tenkeyless, MX Black

I pasted that 6 from a text document I rummaged around for.. LOL
This is after I cleaned the keyboard earlier today but only noticed this a few minutes ago. I only popped off most of the alpha keys and gave it a light brushing - didn't even touch the numbers, so I don't think that had anything to do with it.
Unplugged, re-plugged and still doesn't work. 6 works on another keyboard so it doesn't seem to be a weird software glitch.

Nevermind.. I just hit it hard and it works again. -_-;
And yes, I'm still posting this because I already typed it out and don't want it going to waste.

What a weird thing for it to do though. Repeated presses (even hard presses) didn't seem to help, but one good wack and it works. Gotta show it who's boss, I guess.
