Here is a replacement I wrote for Session Handeling.

Before use, you must replace "[--PATH-TO-SESSION-FOLDER--]" with the path to where sessions should be stored.  Make sure to set the proper permissions for that folder :)

<?
 class Session
 {
  function _makeid()
  {
   $time    = time();
   $ip      = $_SERVER["REMOTE_ADDR"];
   $agent   = $_SERVER["HTTP_USER_AGENT"];
   $md5 = md5($time.$ip.$agent);
   setcookie("SClass", $md5);
   return($md5);
  }

  function getid()
  {
   $md5 = $_COOKIE['SClass'];
   return($md5);
  }

  function start()
  {
   $id = $this->getid();
   if (!$id) { $id = $this->_makeid(); }
  }

  function _getfile()
  {
   $file = $this->getid();
   $file .= ".ssn";
   $file = "[--PATH-TO-SESSION-FOLDER--]".$file;
   return($file);
  }

  function _setdata($data)
  {
   $file = $this->_getfile();
   $fs   = @fopen($file, w);
   if ($fs) { fwrite($fs, $data); fclose($fs);}
   if (!$fs) { return(FALSE); }
  }

  function _getdata()
  {
   $file = $this->_getfile();
   $fs   = @fopen($file, 'r');
   if ($fs) { $data = fread($fs, filesize($file)); fclose($fs); return $data; }
   if (!$fs) { return(FALSE); }
  }

  function set($key, $value)
  {
   $data          = $this->_getdata();
   $data          = base64_decode($data);
   $array         = unserialize($data);
   $array["$key"] = $value;
   $newdata       = serialize($array);
   $newdata       = base64_encode($newdata);
   $this->_setdata($newdata);
  }

  function get($key)
  {
   $data = $this->_getdata();
   $data = base64_decode($data);
   $array = unserialize($data);
   return($array[$key]);
  }

 }
?>

--------------------------------------------------------------------
Useage:

 $Session = new Session();
 $Session->start();
 $Session->set($key, $value);
 $sessionvalue = $Session->get($key);
