Problem with who

[aal1]

Hello,

First, thank you for maintaining such a useful program like who.

My problem is that users are showing up the output of who that are not
logged in.  The output of ps shows that the users reported to be loged in
by who have no active processes (or orphined processes).  Also, the users
that the comman w shows differs from who.  The command w shows users that
have processes that show in ps.

#] who --version
who (coreutils) 4.5.3

#] ps --version
procps version 2.0.11

#] w -V
procps version 2.0.11

Is there something that I am missing?
