SYMPTOMS

In your environment, you configure a Group Policy setting to prevent the tabs in Internet Explorer from closing. You expect that, when a tab is closed, a dialog box appears and the tab is prevented from closing. However, on a computer that has Internet Explorer 9 installed, the Group Policy setting does not work.

CAUSE

This problem occurs because Internet Explorer 9 introduces a new feature, known as fast tab shutdown, that hides a tab during shutdown. Unfortunately, the code that executes fast tab shutdown runs before the Group Policy Object settings are queried. Therefore, the tab in Internet Explorer 9 is hidden but is not successfully closed.

RESOLUTION

To resolve this problem, install this update.
