Everytime I try to chat with someone who is either uploading or I am downloading from all I get is either Host is unavailable, or nothing happens with no chat window appearing.

Is this because perhaps that each of those users may have their chat disabled? I find it strange though that all have been unsuccessful so far.

Any ideas please.

Chat is the most unused feature in LimeWire, it didnt work out well

Ok, many thanks...........

it also might mean the host turned off the chat feature. Most users find chat functions annoying while downloading and turn it off. If the chat smile icon is not showing that means the host disabled it. For instance, I turn mine off as I dont want to chat while Im search and or downloading. Its a pretty useless feature.
