[flexcoders] AIR - Create windows skin accordind Os (Mac/Windows)

[isa_loyer]

Hi, 

I' create a window skin for my AIR application.
Close, maximise and minimise button are on top right and look like Windows 7.

But , mac user are desapointed, so my question is : is it possible to apply a 
different window skin according user Os.

If yes, how to do that.

Thanks
