PC Anywhere does not disconnect even after 60 minutes of inactivity after setting the disconnect if inactive is set for 10 minutes

While using PC Any where for file transferring a file more than 50 GB (approximate transfer time is around 80 min) ,if we have enabled the "disconnect if inactive"  and set to 10 Minutes.Even when file transfer is happening the host disconnects ,will pcanywhere doest not consider a File transfer as an activity.Please guide me if any configuration is to be done.Thanks in advance.

One more separate issue is that PCanywhere does not discconnet if the time set is 60 minutes.Even if no activity is going on still there is not disconnection from the host.If we set the time less than 30 minutes it works fine.
