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.
