Hmmmm... Tried again here at work. Let it run for 5 minutes and nothing. Script still open and cursor at a blinking line.
KIX32.EXE using just under 5MB in the process but does not increase or change. CPU activity not affected, so seems it's just stuck waiting for something.

A normal NETSTAT from DOS returns in a couple seconds.

Don't have time right now to debug but maybe weekend or later next week.

Hopefully someone else can try it out and see what their results are.
