disconnect time

Hi all,

When a thin client loses its network connection it automaticly hangs on the current session for 10-15 seconds and then disconnect from it with an error message that the connection has been lost. It will reastablish the connection automaticly after 30 seconds.

Is it at all possible to change the time it takes before it desconnects to 60 seconds or so? This would mean that when the network fails for 30 seconds or so the users would just get stuck in their session for max 60 seconds and not have to log in again.
