The urge to grab one of these (now with TV out) was irresistible, and all is good so far except one small annoyance. The analog nub seems to "click" when moving it around. It works, but it seems to click and make kind of cracking noises when used. I can push on it slightly and it will click. Are they all like this? Did I get a dud? Anyone else have one that exhibits this behavior?
