When you install Microsoft Windows XP Service Pack 2 (SP2), a new object caching feature is also installed. When you compare the values of the two frame.frames properties of an object in Microsoft Internet Explorer, the results may be incorrect, or the values may not be retained.
In Windows XP Service Pack 2, the frames object is now wrapped with a security wrapper. When the new object caching feature is enabled, this security wrapper is applied. Therefore, access to all cached objects is blocked. This may cause the frames object comparison to return false even though the frames are equal.
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To resolve this problem, you can use either of the following methods to restore or to replicate the original functionality:
