title: recaptcha not displaying on FF or chrome, IE displays after allowing blocked content
body: <p>The server that is hosting the code is running coldfusion 4.5.  The page in question is a frameset, so I can't link directly to it.  </p>
  
  <p>It's this page: <a href="http://www.palosverdes.com/calendar/" rel="nofollow">http://www.palosverdes.com/calendar/</a>, and then the sign up link on the right under "Admin".  </p>
  
  <p>The code that is there right now works as expected for IE after allowing blocked content.  Here's the code:</p>
  
  <pre><code>&lt;cfscript&gt;
  CHALLENGE_URL = "http://api.recaptcha.net";
  SSL_CHALLENGE_URL = "https://api-secure.recaptcha.net";
  VERIFY_URL = "http://api-verify.recaptcha.net/verify";
  &lt;/cfscript&gt;
  
  &lt;cfif isDefined("form.recaptcha_challenge_field") and isDefined("form.recaptcha_response_field")&gt;
  
  &lt;cftry&gt;
      &lt;cfhttp url="#VERIFY_URL#" method="post" throwonerror="true"&gt;
          &lt;cfhttpparam type="formfield" name="privatekey" value="6LfwVs0SAAAAAIlIJpLDvIay_d5G0RncS0VSrnV0"&gt;
          &lt;cfhttpparam type="formfield" name="remoteip" value="#cgi.REMOTE_ADDR#"&gt;
          &lt;cfhttpparam type="formfield" name="challenge" value="#form.recaptcha_challenge_field#"&gt;
          &lt;cfhttpparam type="formfield" name="response" value="#form.recaptcha_response_field#"&gt;
      &lt;/cfhttp&gt;
  &lt;cfcatch&gt;
      &lt;cfthrow  type="RECAPTCHA_NO_SERVICE"
          message="recaptcha: unable to contact recaptcha verification service on url '#VERIFY_URL#'"&gt;
  &lt;/cfcatch&gt;
  &lt;/cftry&gt;
  
  &lt;cfset aResponse = listToArray(cfhttp.fileContent, chr(10))&gt;
  &lt;cfset form.recaptcha = aResponse[1]&gt;
  &lt;cfset structDelete(form, "recaptcha_challenge_field")&gt;
  &lt;cfset structDelete(form, "recaptcha_response_field")&gt;
  
  &lt;cfif aResponse[1] eq "false" and aResponse[2] neq "incorrect-captcha-sol"&gt;
      &lt;cfthrow type="RECAPTCHA_VERIFICATION_FAILURE"
          message="recaptcha: the verification service responded with error '#aResponse[2]#'. See http://recaptcha.net/apidocs/captcha/ for error meanings."&gt;
  
  
  &lt;/cfif&gt;
  
  
  
  &lt;cfelse&gt;
  
  &lt;cfset form.recaptcha = false&gt;
  
  &lt;/cfif&gt;
  
  
  &lt;cfif isdefined("form.recaptcha") and form.recaptcha neq "false"&gt;
  &lt;cfinclude template="addorgresults.cfm"&gt;
  &lt;cfelse&gt;

  <p>I've used this page <a href="http://www.palosverdes.com/sandbox/captchatest.cfm" rel="nofollow">http://www.palosverdes.com/sandbox/captchatest.cfm</a> to determine that the captcha itself is working correctly, so my guess is that it has something to do with putting the captcha in a frameset.  Any ideas?</p>
