HOTFIX: The exception handler may not catch an exception in Internet Explorer 7 or in Internet Explorer 6 when you view a Web page that throws an exception from a function that is called through the expando property
You develop a Web page that throws an exception from a function. The function is called through the expando property of a DHTML object. When you use Windows Internet Explorer 7 to view the Web page, the exception handler may not catch this exception.
Note This problem also occurs in Windows Internet Explorer 6 when at least one parameter is passed to the function from which the exception is thrown. To work around this problem in Internet Explorer 6, see the "Workaround" section.

The "Intranet Sites: Include all local (intranet) sites not listed in other zones" policy setting does not function as expected in Internet Explorer 7
Consider the following scenario:
• You are running Windows Internet Explorer 7 on a Windows-based computer.
• In a workgroup environment, you use Group Policy to disable the Turn on automatic detection of the intranet setting and to enable the Intranet Sites: Include all local (intranet) sites not listed in other zones setting.
• You use Internet Explorer 7 to access a local intranet site.
In this scenario, the local site is displayed through the Internet zone instead of through the "Local intranet" zone as expected.
