Hi again argv0, Ok this is what I've tried:

1. downloaded v7.1 of mIRC and installed as an upgrade over the script I have now - no luck - IP Address still empty. When I enter the IP Address myself I can still do a manual DCC Send and initialize DCC Chat but not respond to DCC Requests. This is so frustrating.

2. did a clean install (to new folder) of just mIRC as a portable app - no luck - IP Address still empty.

Of course I have no idea if there are any other settings I need to make since it's a new version.
