flex 3.0 StyleProxy

It was when developing the PositionedTabNavigator that I first came across StyleProxy and there seemed to be very little information on it.

Doug just sent me a link to a post by Joan Lafferty, titled Upcoming Changes to Flex Styles (codename:Moxie). This is a much better approach to styling, but also worth a read so you understand why your application may look different in Flex 3.0.
