Thank you Robin, I was about to suggest the same about fitting a rod under the keyboard, I have done the same in Darwin Australia and have never had further problems with sticky actions. Some one once said that you don't fit Dampp-Chasers to fix sticky actions, only to keep the pitch constant but believe me, the customers just want to play their pianos knowing that the piano is out of tune a little (or a lot) is natural in this humid weather.
