SUMMARY

This article describes an issue where pop-up windows may still appear, even though the Pop-up Blocker feature in Microsoft Windows XP Service Pack 2 (SP2) is turned on. To resolve this issue, you must either remove the Web site from the Trusted sites or the Local intranet Web content zones, or you must click No when you are prompted to run ActiveX controls.

SYMPTOMS

After you install Microsoft Windows XP Service Pack 2 (SP2), pop-up windows may still appear, even though the Pop-up Blocker feature is turned on. (The default setting of this feature is on).

Note To determine if the Pop-up Blocker feature is turned on, click Internet Options on the Tools menu in Microsoft Internet Explorer, and then click the Privacy tab.

CAUSE

This issue can occur when one of the following conditions is true:
  • You click a link that opens a pop-up window.
  • The Web site where the pop-up window originates is either in the Trusted sites Web content zone or the Local intranet Web content zone. Because Web sites in these zones are considered safe, their pop-up windows are never blocked.
  • The pop-up window is opened by software that is running on the computer.
