  Additional notes to my workaround on Q266305:

  I have tested my findings with PDF, XLS, DOC and ZIP. However JPG and 
GIF didn't make IE pop up the download box.  By changing content type 
from "octet-stream" to "force-download" (or some undefined type), it 
will work. Of course, we need to take care of other browsers too. Here 
is the improved code, hope it helps:

  header("Content-type: application/force-download");

  if (strstr($_SERVER["HTTP_USER_AGENT"], "MSIE"))
    header("Content-Disposition: filename=$myfile" . "%20"); // For IE
  else
    header("Content-Disposition: attachment; filename=$myfile");     // 
For Other browsers

  Note: If you are using session together with this download, you will 
need to add the following line BEFORE the code above to make IE work:

  session_cache_limiter("");



======


It (or some other voodoo) got my thing working.... good luck.

Of course, while you're there you'll also find an endless discussion of 
."%20", other IE 6, 5, 4, 3, 2, 1 and Opera on my Highly Customized 
Toilet discussions....
