Flex Calc v1.0

Normally I would be crazy for writing something like this. Especially when any real operating system already has a much better calculator that comes installed by default. I admit that Flex Calc is not exactly the best calculator in the world. But, the real purpose of excercise was to begin learing the Flex 2 language. Also, once you click the panel you can also use the keyboard. Enjoy, and please let me know if you see any bugs.
