This is a known issue in general for the Cygwin/X folks, specifically for
ZoneAlarm, although you'll see some conflicting reports. Your finding that
the firewall needs to be uninstalled to avoid the problems is quite true.
Firewalls insert themselves into the networking stack. Turning them off
does not avoid any buggy code that they have inserted. Only uninstalling
returns the stack to its original form, eliminating the bug. If you were
using the latest version of ZoneAlarm, you may want to consider reporting
the problem to them if you have not already.
