Internet Explorer 6 is accidentally disabled when you access a webpage that uses a custom pop-up object.

A few days ago, I suddenly found that an IE exception occurred when the right-click menu was disabled,

Symptom:

When you access a webpage that uses a custom pop-up object, Microsoft Internet Explorer 6 closes unexpectedly and generates an error in the mshtml. dll file. This problem occurs when Security Update 2003 is installed on a Windows XP Service Pack 2 (SP2) or Windows Server 918899 Service Pack 1 (SP1)-based computer. If this problem has serious impact on you, you can fix it.Program. Otherwise, we recommend that you wait for the next Internet Explorer Cumulative Security Update.

Cause: A regression error exists in Security Update 918899. Details: http://support.microsoft.com/kb/923996/
