This is an Internet Explorer Bug. Search the Microsoft Knowledgebase.
It has something to do with the caching headers.

this isn't just an issue in https and windows, its also http, and also
on linux. If you have session_start in there and just put out a
content-type and content-disposition, it will barf on you if you try to
choose "open" instead of "save" .. "save" works fine. If you take out
the session-start() it works great. If you use the headers trick noted
two posts up, it also works great. 

Tested under ie4/5/5.5/6 ns4.78/4.79/6

Apache 1.3.26 and PHP 4.2.1 

I also came across this issue, and [EMAIL PROTECTED] headers (minus
the last one) FIX the problem.  However in trying to tack down the
issue I found that taking out the session check on the page also fixed
the problem?  It seems odd that using sessions would change the
behavior of IE.

The "magic" headers that [EMAIL PROTECTED] do work, but note:
header("Pragma: ");
header("Cache-Control: ");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");  //
HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");        // HTTP/1.0

Does not work because of the last header !!
It works when I comment it out !!

This is not just IIS related.
I run Apache 1.3.26 on Linux (RD7.2) and PHP 4.1.2 and I also suffer
the problem.
I believe it is just related to IE clients.

And 
header("Pragma: ");
header("Cache-Control: ");
does not work for me.

I also believe the problem is that headers are corrupted.

Pedro.
