I've recently started cubing again, so this means I broke out qqtimer for my solves. But for some reason, whenever I start the timer with the spacebar, it ends after no more than 5 seconds on its own. cstimer and others have done the exact same thing. I'm not sure what could be wrong with my keyboard itself, because I've never noticed a problem before now, but I'm almost sure it's a keyboard or computer issue. Any thoughts?
