curl_easy_setopt(http_handle, CURLOPT_URL, "ftp://b3_15536782:tester@ftp.byethost3.com/htdocs/index2.html");
there is no space. Like I said the problem is windows only, on my mac it works fine.

Also if I remove the following code
rc = select(maxfd+1, &fdread, &fdwrite, &fdexcep, &timeout);
switch(rc) {
    case -1:
      /* select error */
      break;
    case 0:
    default:
      /* timeout or readable/writable sockets */
      curl_multi_perform(multi_handle, &still_running);
      break;
    }
And replace it with just
curl_multi_perform(multi_handle, &still_running);

It still works.
