I don't think we've changed the wind symbols; in what situation are they being displayed differently?
I also see this problem:
When running InFlight on my WinCE (Airspace Aware) device the wind barb (shown in the box on the map window) is now too thick (line width) to make out how many feathers there are on the tail of the barb as they now merge into a single blob on my small screen (anti-aliasing?). BTW this is on the 2.3 beta version 23/2/2012.
It would be nice if when in 'track/course up' mode the wind barb could rotate to show relative wind direction (I think the barb is currently always drawn 'North up').
