PHP, IIS 7 and Buffering

[Uglybob1]

Hello, I currently installed php on Windows Vista with IIS 7.0.  For what I am using, everything seems to be working as they did in IIS 6 except for buffering/flushing.  I have a small timer which refreshed the browser every second with a count down, but it seems it does not flush with IIS 7 until the entire page is finished.  I still have the IIS 6 box up which is running the exact same code and I even copied over the same php.ini file so I am thinking it has to be something with IIS 7.  Has anyone run into this problem and/or know of a fix?  Here is the code if need be...

  private function pause($seconds = 1, &$count, $display = FALSE) 
  {
    if($seconds < 0)
      out(__CLASS__."->".__FUNCTION__."(): Parameter seconds($seconds) can not be less then zero<br>");
    else
    {
      $startCount = $count*$seconds;
      for(;$seconds>0;$seconds--)
      {
        if($display && $startCount > 0)
          echo " ".($startCount--);
        ob_flush();
        flush();
        sleep(1);
      }
    }
  }

...so basically it outputs something like  5 4 3 2 1, flushing after each number.  But in IIS 7 it doesn't flush until the entire page is written.

 

Thanks in advance for your time!
