Thanks. I'll pay more attention to the temperature changes to get a better picture of what I'm dealing with. Come to think of it, I usually turn up the heat just before I go into the room with the piano. I have a similar problem with my tuning fork. Between handling it and setting down and handling it again, its pitch changes quite a bit. TuneLab doesn't seem to have that problem. :)
