Consider the following scenario:

• You have a computer that is running Windows Vista or Windows Server 2008.
• The computer has the User Account Control (UAC) and Internet Explorer 7 protected mode enabled.

In this scenario, Internet Explorer 7 may stop responding when you try to visit any Web site. When this problem occurs, a blank Internet Explorer window appears, and the pointer circles constantly. To escape this condition, you must end the Internet Explorer process (Iexplore.exe) in Task Manager. Or, you must restart the computer.

Notes

• Typically, this problem occurs the first time that you start Internet Explorer after the computer starts or when the computer resumes from sleep or suspend mode.
• Sometimes, the Internet Explorer does not start when you double-click the Internet Explorer icon.
