Problem with Identity Safe Cards

Hi,

 

I have 2 logins on my Windows XP PC, one named Tom and one named Joan.  While logged in as Tom, I created an Identity Safe Card also named Tom.  Likewise, while logged in as Joan, I created and Identity Safe Card named Joan.  When I go to a website while logged in as Tom, it asks me if I would like to use the Identity Safe Card named Joan?  When I go to a website logged in as Joan, it asks if I would like to use the Identity Safe Card named Tom?  Why is NIS associating the wrong Identity Card with the login?  How do I fix this?

 

Thanks!
