Look back function

[3rd.Rail]

I am up to date on the version installed.  I have three profiles to the key. One profile is the default -unnamedprofile-, I have never used it.  The other two profiles I use regularly. The look back function only works in one of these profiles.  Is this normal?  While I am happy that the function works in one function period I thought I would let you know what I am experiencing.  I am using a higher end PC with strong graphics capabilities.
