- Scripting errors which prevent the analysis of cookies after they are set
- Variables in the Janrain script which conflict with Google Analytics variables (particularly variables named

or_gaq
) - Extensive use of cookies for storage which may overflow the allowed cookie sizeallowed cookie size (and flush out the cookies set by Google Analytics)
