FCK Editor losses web session when open dialog box

I use IE 7, and FCKEditor 2.4.3

When i open the "Browse Server" dialog box, the session is different with the page session.

Here is the code i added into my config.php in connector folder:

session_start();
$sStorePath = $_SESSION['StorePath'];

global $Config ;

// SECURITY: You must explicitelly enable this "connector". (Set it to "true").
$Config['Enabled'] = true;
$Config['UploadEnabled'] = false;
$Config['CreateFolderEnabled'] = false;

// Path to user files relative to the document root.
if($sStorePath != '')
{
   $Config['UserFilesPath'] = '/'.$sStorePath;
}
else 
{
   $Config['UserFilesPath'] = '/userfiles';
}

I have check the session ID when opening the dialog box is different with the main page session ID.

It works fine when Im using Firefox, but it is a big problem when Im using IE.

Could you help me arount this problem fast.

Thx
