A while back I needed to do this kind of thing for a map of the U.S., where
rolling over a state triggered a variety of actions. I ended up having two
map graphics as cast members, both the same size. The pretty one was
displayed on stage, and the other was used only for rollover tests. In
photoshop, I created the second map by filling each state with a unique
solid RGB color (avoid antialiasing). By mapping the mouseloc on the
"staged" image to the offstage map image and testing with getpixel(), I
could check against a prop list of names (props) and rgb values (values),
and return a name for a specific colored area. Once I had a name, I could do
whatever I needed with the info.

This is a bit work intensive, however (when compared to using invisible
rects, for example), and I only use it when I need a relatively high degree
of accuracy in the rollovers.

hth,
Kurt
