Basic question 1 - Traffic

A few months ago I successfully installed Cygwin on my Windows 2000 PC 
and on my Windows XP laptop, and I have recently started using Cygwin/X 
to run a building simulation program called ESP-r (developed over many 
years at the University of Strathclyde in Glasgow - see "Software" at

No doubt this is a very basic question, and I'm not sure whether it is 
really a question for this group or whether I should direct it to the 
authors and/or user group of the ESP-r software, but I wonder whether 
someone could shed some light on why Cygwin/X (or perhaps it is just the 
individual components of the ESP-r software I am running?) triggers 
ZoneAlarm access permission alerts and generates constant internet 
traffic (or perhaps only 'trusted zone' traffic?) as indicated by ZoneAlarm?

Thank you.
