Issues with coldfusion.navigate (CF9) in Safari & Chrome

I am using Coldfusion 9. I have a ColdFusion.navigate call in a cfdiv tag located within a Cflayout tag (type tab).

The following piece of code is located in a file called "inc_shjobs.cfm" and is being called using the src attribute from a Cflayout tag on another page:

<script>
        ColdFusion.navigate('inc_shjobs.cfm?morejobs','jobs1')
  </script>

<cfdiv id="jobs1">
<form name="ne">   
    <table width="98%" cellspacing="1" cellpadding="6" border="0" bgcolor="white" >
      <tr>
        <td colspan="1" align="center"><br />
       
<input type="submit" name="morejobs" style="font-size:1.4em; font-style:bold " value="Expand Job Search" onClick="javaScript:ColdFusion.navigate('inc_shjobs.cfm?morejobs','jobs1');    "></td>
      </tr>
  </tr>
        
  <tr><td><br /><br /></td></tr>
       <tr><td valign="top">
             <strong>Search Within</strong> <select name="radius" >
      <option value="0" <cfif session.trn.jsradius is 0> selected</cfif>>0 miles</option>
      <option value="5" <cfif session.trn.jsradius is 5> selected</cfif>>5 miles</option>     
      <option value="10" <cfif session.trn.jsradius is 10> selected</cfif>>10 miles</option>           
      <option value="25" <cfif session.trn.jsradius is 25> selected</cfif>>25 miles</option>                 
      <option value="50" <cfif session.trn.jsradius is 50> selected</cfif>>50 miles</option>                 
      <option value="100" <cfif session.trn.jsradius is 100> selected</cfif>>100 miles</option>                 
      <option value="-1" <cfif session.trn.jsradius is -1> selected</cfif>>Statewide</option>                 
      <option value="-2" <cfif session.trn.jsradius is -2> selected</cfif>>Nationally</option>                 
      </select>
    <input type="submit" name="rad" value="Go" onClick="javaScript:ColdFusion.navigate('inc_shjobs.cfm?radius='+ne1.radius.options[radius.selectedIndex].value,'jobs1')">  center of  <strong><cfoutput>#session.trn.city#</cfoutput></strong></td>
     
<td  valign="top"><a href="dsp_jobresearch.cfm" ><img src="images/justjobs1.gif" alt="Just Job Search" border="0" /> </a></td>
         </tr>
    </table>
    </form>
    </cfdiv>

In IE and FF, it behaves approriately by loading only the div. In Chrome and Safary, it reloads the entire page and ignores the parameters. When the same code was run under CF8, it also worked.

Anyone got a clue as to why?

Thanks!
