Adium

Adium might work... as I think the PC counterparts Gaim and Pidgin also support MS forms. (at least works for jabber)

MSN would be nice, but it is Microsoft that we are talking about. Apple has very limited ties with them (only with the iPod + iTunes, BootCamp, and more recently, Safari). I don't see why they would offer it. MSN is available for iChat via Jabber, but I don't think it allows for audio/video chat. Adium is nice and that should have the audio/video support soon.

I REALLY want native support for MSN in iChat AV. This means Audio, Video, AND Audio/Video conferencing. Also including custom display names, now playing, ability to save and use custom emoticons, ability to change contact names based on Address Book entries. iChat AV is a great app, it's just a shame that I have no use for it because virtualy none of my friends use AIM. And...

default apps that were running at the time include Firefox, Thunderbird, Adium ... that's probably it. X11 and Terminal were also running. ...

minutes ago while using Adium and Safari, my MacBook Pro shut down without any warning. I tried to boot up again but it got past the 'chime' and shut down again. ...

I've tried reinstalling both Adium and Camino but it didn't seem to make a difference... Just wondering if anyone has any clue as to why this would happen. ...

And if you don't need the video, Adium is your friend. ...

Already use Adium. :) I have the sound disabled on it, so It's probably not a issue.

I hardly ever used iChat, but I am always in Adium, so if you want to chat my screen name is "sigtris@yahoo.com

I had a problem similar too this when using AIM (AOL instant messenger) a few years ago. Is your IM program AIM? if so, try using something else like ichat or adium.
