Alan,

IF I'm not mistaken, this model has wood action parts.  

I know you said the flanges seemed pretty mobile, but I'd pull the action and check the wippen flange.  Based on your description of the problem this seems like a possible cause.  I've seen it more than once in Kawai uprights.  It's hard to tell whether there's any binding or not without removing the parts.

I would pull action and turn action on side.   Lubricate damper lever felt (spoon/felt contact points) with protek.

Nice little Kawai CE-7 in like-new condition, all clean and well regulated. Customer complains of a key (G2) that sticks. 

1. It does, occasionally, stick but only if you hold down the sustain pedal and then play the note. 
2. The key releases/resets when you lift the sustain pedal.
3. It is NOT the keystick or rail bushings. You can remove the keystick and still make it fail just lifting the whippen--but only if the sustain pedal is down. So ...
4. It is not a capstan height issue, either.
5. Examined the damper felt and the spoon, they are like new. Flanges seem plenty mobile.
6. The damper, itself, does not seem to interfere with its neighbors; nor does it lift any earlier or later.

Actually, she would hardly have noticed it, since it only sticks when you theoretically want the note sounding, anyway; but she overuses the sustain mightily. (Chord change? What chord change?)

Any ideas would be appreciated
