Overcoming overlapping (obscured) map areas

[Adrian Williams]

In trying to create a clickable map (using a graphic of a blob of ink),
I encounter problems with overlapping areas when using the HTML method.
It is to be viewed online, but an application may do just as well.
The red areas that get highlighted at MouseOver represent letters of  
the alphabet.

In html, MouseOver a large area and the graphic is obscured by smaller  
areas that are on top...

A and C are OK because they are on top of each other.
J is obscured at the bottom tip.
Ideally, when J is highlighted, the whole of the tip should also be red.

Can Rev offer a better solution?
If the MouseOver triggered the display of another layer (instead of  
just another image on the same page) it would work.

Thanks,
Adrian
