[flexcoders] How to set rounded corners on an Accordion container

[Brad O'Hearne]

Hello all,

I am trying to create rounded corners on an accordion container, and I  
have discovered that if I set the corner radius, I get rounded  
corners, but I can also see a rectangular corner and background behind  
it. Does anyone know how to achieve rounded corners in an accordion  
without additional artifacts?

Thanks,

Brad
