dropping connection

Hi,
I have a fellow assocate that uses pgAdmin3 remotely (he is in GA the DB is in 
CA).  He insists that a "time out" is somewhere in pgAdmin.  He loses 
connection often.  It has happen while are talking on Skype, or not talking 
on Skype.  It's also has happened while I was remotely connected.  The point 
being that other programs using the internet do not appear to disconnect.  I 
too have experienced a disconnect.  However, I have always blamed the poor 
internect connection I had at the time (like at a hotel).

Is there such a setting (time out) that controls pgAdmin3 connections?  I 
don't experience any disconnects but I'm on the lan and he's using the wlan.
