Run As Administrator on XP/2003 is not the same as Vista/2008's run with
elevated privileges.  Run as Administrator means login as the
Administrator account which is a new logon session and is intended to be
a new logon session.

Credentials should not be shared between the two accounts.  

The same is true if you use a non-Administrator account on Vista and
choose Run as Administrator.  In that case, you are using a new logon ID
and the logon sessions should be separate.  There is no bug here.  This
is the desired behavior.
