digsby is a multiprotocol IM client that lets you chat with all your friends on AIM, MSN, Yahoo, ICQ, Google Talk, and Jabber with one simple to manage buddy list.
We just pushed out a small update (Build 80, r27822) which compensates for a protocol change in Hotmail (Windows Live Mail) which caused login to get stuck in the “Authenticating” state. As always, you can read the entire list of enhancements on our Change Log.
