Keyboard and Mouse have been inactive for x minutes

When attempting to connect to the host,  it is usual to see the above message. If the mesage reads <10 minutes, it is reasonable to assume in my organisation that another user is using the host machine. If that is the case I normally try again in about 15 minutes

There are occasions when I attempt to log back in ( after 15 mins) and the message now reads  ' Keyboards and Mouse inactive for 16minutes'.  So I assume the person using the host finished  about the time I tried to connect first time. Logisticaly it is improbable. but not impossible for a user to be using the host at some specific times and I wonder if the Logmein timer records an attempt to connect remotely as the use of the host Keyboard and Mouse?
