PHP Download problem...

PHP problem ...
secure download script ...

http://localhost/getfile/?DFID=253&filename=/BOB-1.1-11.zip

Which sets up a file for download that isn't available publicly ...

Now my problem is IE wants to rename that file to ...

BOB-1[1].1-11.zip

My script is sending the following headers ...

  header( 'Pragma: ' );
  header( 'Cache-Control: ' );
  header( 'Content-Length: $contentLength' );
  header( 'Content-Type: $mimeType' );
  header( 'Content-Disposition: attachment; filename="'.$filename.'"' );

Anyone got any ideas ?
I know its an issue with IE wanting to change the version of the filename due to the numbers in the filename ... and no changing the filename isn't an option
cheers
