I have this issue as well on my '12 air. It doesn't so much get stuck but it ccccccccccc (sorry, I was testing it) does emit a slight click and it almost sounds like there's a bit of crunchy food behind it (though there certainly isn't). I'm hoping it will be ok, as it isn't consistently happening at the moment... but I'd like to hear if others are having this issue as well.
Edit: Can you add the 11" to your tags as well, as this is the model I have?
