I tried gently flexing it as you recommended, and flexing it a bit to the left and slowly releasing seems to remove the click temporarily (it seems like it creeps back in after a number of less careful presses). I suppose that means there's some kind of small alignment problem and maybe the 'default' position is not quite right? At any rate I think I will take a while to feel out whether it remains reduced/removed/controllable or creeps back in right away during normal play. Thanks so much for the suggestion, though, I didn't realize I'd be able to do anything about it on my own at all.

My long-anticipated PX-560 arrived new with a single key (F2) that makes an audible "click" when it pops back up. The click is faint, but distracting. Returning it wouldn't be a simple task for me, so I'm trying to decide whether this is something I can live with. Obviously the instrument shouldn't click right out of the box and I probably have the right to a return, but presuming I really don't want to go through the hassle of returning it, is clicking an inevitable element of wear and tear that I could expect to eventually start popping up in other keys if I owned the instrument for a few years, or is it a major flaw that simply shouldn't be happening?
