Hi, long time lurker but first time post - and of course it's with a problem 

The spacebar on my relatively new HHKB Pro 2 feels a little loose on one side (the side I hit the most).  There's a little 'give' before the key action actually takes place which makes it noisier and cheapens the feel.
Based on a cursory search through the forum I can't find any similar complaints, but is this something that anyone's come across before?  Is there a fix or is it just a trait of these switches?
