We upgraded to 5.0.4 this past weekend. Now IM won't connect to the Yahoo service for some reason. Was there a change made to IM that wasn't listed in the release notes?

I found that when I try to make a connection and it fails, the zmmailboxd.out log gets an entry that looks like this.

Response is: 0

Not much help there. The UI window just tells me "Connection FAILED: Incorrect username or password", but I can login from my desktop using another IM client just fine with the same username/password.

Anyone know?
