Image map leaves a stroke around link area
I'm far from a DW advanced user but I'm creating a html file for a client with an image map over an area of an image that looks like a "Learn more" button. So it works fine and takes the viewer to a web page in a new tab window, per the link I was given but…when you click the tab contaning the html with my image map, there is a faint stroke in the shape of the image map around the hot area. The client doesn't like that and questions what is wrong. So if you click elsewhere in the window it disappears.
How do I get rid of that outline left behind???
