What is the best way to make just a specific area(s) of a graphic a clickable link?

acorn said use 0px as line width, and that is what you should do, enter 0 in the line width box - if you entered none then that is your issue
none means you don't see anything at all; 0 means no outline in render, buts shows a visible path during design

@handrawn - thanks.
@Nancy, as @handrawn says, 0px shows as a 1px line at whatever scale on the design page only.

The No Fill approach beats the 99% Transparency as that fades out any Line width so it is hard to see the extent of the shape.

The down-side is you can only marquee select a No Fill shape or select it by clicking on its Line.
A 99.5% Transparency is also very hard to catch; a 99% Transparency Black can just be seen.
