I know this is one of those incredibly stupid questions but i just cant see the obvious.

The user guide says just click on the button, and i remember a button in previous limewire versions but there is none now. Only Download, Browse Host and Stop. Even when i highlight a hit with a chat face on it, no button appears.

Is something turned off on my configuration?

So how do you chat?

the button is gone in LW 4, so your question is not stupid.

Chatting is now a control-click option
