If I draw a circle using the Graphics and Shape classes, and then add
the shape to a sprite, I can use the sprite for the hitArea of another
sprite and it works just fine. Everything within the circle is a hit,
everything outside of it is a miss.
However, if I create a sprite containing a Bitmap drawn from this same
circle and try to use this sprite for the hitArea, the entire rectangle
becomes the hit area. I've played around with different alpha-levels,
using white and black, and using the opaqueBackground setting. Nothing
seems to work. Am i missing something or is this a known limitation?
I'm using AS3 under Flash CS3.
