Hi,
please, take a look to the next code:
http://jsfiddle.net/mp3man/sn0gdsfa/1/
The problem with this code, is that when you click over the
"green_layer", the "red_layer" click is catched too,
and this is what to avoid. There's any way to do it, without
changing the html context?
Many thanks,
Dani
