Scale a rounded rectangle without changing roundness in flash

Hi,

Could someone please tell me how to: Scale a rounded rectangle without changing roundness - So as the corners stay the same?

 Can I achieve this and be able to scale on one axis – not constrain proportions?

I have tried dissecting the corners from the main part of the rectangle and putting them in separate m/c’s etc.

This site does an excellent job - go to options and you can dynamically change the roundness of each window
