Yahoo Chat!
 

Anyone else use this and have some issues getting it started? I just installed it yesterday and everytime I connect. not sure why but if i right click when in the chat window. It will disc and drop to desktop and close the messanger too. Its very annoying. their help is lacking and no one seems to be able to get me any answers.
As much as i hear its good for hosting Web chats.. I would rather just use MSN.
