Extra tab opening in Browser

Question

I have an image with a rectangle map area and when clicked, I'm wanting a new window showing the html page for that link. For some reason, it is not only opening the html page but also a new tab in my browser. I have tried it in both Safari and Firefox with the same results. How do I get the tab to stop opening? Here is the code to one of the links:
<p><img src="http://www.renegadescookingteam.com/images/2010_2011.gif" alt="2010 and 2011 image" width="150" height="25" border="0" usemap="#Map" />
      <map name="Map" id="Map">
        <area shape="rect" coords="18,7,52,17" href="javascript:()" target="_blank" alt="2010 image hotspot" onclick="MM_openBrWindow('http://www.renegadescookingteam.com/2010.html','2010 Underwriters','width=620,height=700')" />
        <area shape="rect" coords="94,6,127,18" href="javascript:()" target="_blank" alt="2011 image hotspot" onclick="MM_openBrWindow('http://www.renegadescookingteam.com/2011.html','201 1Underwriters','width=620,height=700')" />
      </map>
    </p>
Any assistance would be greatly appreciated.

Answer 1

On all your image map tags, remove this:
href = "javascript:()"
Your javascript definition already defines what to open and where to open (new window in your case - modern browsers consider it as tabs, depending on user preferences). The href tag is redundant here.
But, this will also remove 'hand' cursor.
To add the hand cursor, add this to your sponsors.html file under #sidebar1 (line 31):
cursor: pointer;
Your issue should get resolved.
