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 method.
