From the developer:
AirState tries to maintain a valid psychrometric as you edit values. Clearly this is not always possible since you may change the wet bulb to a value greater than the dry bulb with the intention of changing the dry bulb next. You will notice that the program always tries to use the last values that you entered.
You may want to check out more software, such as f x -Viewer, Trachtenberg Speed Math or MathMatic, which might be related to AirState.
