Recording Yahoo Messenger Voice chats.

Hello,

Can anyone suggest some software to record voice chats through Yahoo Messenger on my PC ???

I'm using Yahoo Messenger 8.0 on Windows 98SE.

I have a software name 'All Sound Recorder' but it is unable to record voice chats. When I try to run it, I get an error saying the computer's audio is already in use by another device.

Is there a solution to this ? If not, then which software should I use to record Voice chats ???

Thanks.
