Mac IE File download problem - any solutions?

I know this has been addressed before, but I'm wondering if anyone has ever found a solution. The code: header('Content-Type: application/octet-stream'); header('Content-Length: '. filesize($file_info['full_file_path'])); header('Content-Disposition: attachment; filename="' . $file_info['filename'] . '"'); header('Connection: close'); readfile($file_info['full_file_path']); The problem: When downloading certain files on a Mac using IE 5.x, files are displayed within a browser window instead of downloading. This seems to occur mostly with quicktime files (.mov, .mp3). Some quicktime files work, while others with the same extension do not. BTW, after doing some research I changed this: header('Content-Disposition: attachment; filename="' . $file_info['filename'] . '"'); to this: header('Content-Disposition: filename="' . $file_info['filename'] . '"'); but it did not help. I've also tried several other iterations of the above to no avail. Problem #2: if I change the first header to: header('Content-Type: application/force-download'); a save-as dialog box comes up, but it does not carry-through the file name of the file being downloaded - instead it sets the default file name to the name of the script that's being executed (i.e. download_file.php). Any help is, as always, greatly appreciated. -- Daniel Leighton Chief Technology Officer Webolution http://www.webolution.com This email may contain material that is confidential and privileged for the sole use of the intended recipient.
