Pop-up window closes unexpectedly during a download in Internet Explorer 6 (887301)

SYMPTOMS

After you install Microsoft Windows XP Service Pack 2 (SP2) or you install Microsoft Windows Server 2003 Service Pack 1 (SP1), you may experience the following problem in Microsoft Internet Explorer 6.

You open a Web page that has a hidden iframe. Then you click a button that sets the source of the hidden iframe to an ASP page that initiates a file download with the Content-Disposition set to attachment. In the File Download dialog box, when you click any one of the following buttons, the file download is opened, saved, or canceled correctly:

Open
Save
Cancel

However, the window with the iframe that initiated the download closes. This window did not close before Windows XP SP2 or Windows Server 2003 SP1 was installed.

Additionally, you may experience this problem if you are using a frameset that has a simple link to a download URL from a page in the frameset.

This problem occurs only when the page that has the hidden iframe or the frameset was opened by using the window.open method.

WORKAROUND

To work around this problem, initiate the content with window.open instead of inside the iframe on the Web page. To do this, use the following sample script as an example.

You can use the following code to determine whether your computer is running Windows XP SP2.

<SCRIPT>
var bIsXP=false;
var bIsXPSP2=false;
window.onload=fnInit;

function fnInit()
{
   if(navigator.userAgent.indexOf("Windows NT 5.1")>-1)
   {
      bIsXP=true;
   }

   if(bIsXP==true)
   {
      if(navigator.userAgent.indexOf("SV1")>-1)
      {
        bIsXPSP2 = true;
      }
   }

   alert(bIsXPSP2);

   if (bIsXPSP2)
   {
      //do the special code, basically, redirect to the XPSP2 page
      window.location = "page_xpsp2.htm";
   }
}
