My son and I were chatting tonight with Yahoo Instant Messenger, which has a video function. And he and I both have Intel webcams.

So does that program have its videocam drivers?

If it does not, then does that mean XP and 2000 do? Or could Yahoo Instant Messenger have been able to access the drivers in my video/voice program and my son's video/voice program. At the time of our videochat, neither his video program or mine were open?

How does it work?
