Same here, Barbara. Don pretty well nailed it, I think. If an hour isn't 
available, a minimum of 15 minutes will usually take care of it. Also, it's 
helpful to know if the desk will be in place for performance. Lighting 
angles can play a big part in the high treble, sometimes. It sounds like 
your temperature change isn't severe. A 4 cent drift at 440 is less than 5 
or 6 degrees Fahrenheit. The best way to be sure, (and predictable in the 
future), is to measure temps and pitch before, at intermission, and just 
after. I really like my cheapo Radio Shack infrared thermometer, but.... I 
fell in lust with the one I saw at the radiator shop. Way cool, with a 
laser pointer and everything! I didn't ask how much he paid for it, and he 
didn't leave it under the hood!

Good luck,
Guy
