my built in webcam on my laptop stopped working on yahoo messenger.It works on windows live messenger though..how do i get it to work on yahoo again?All i get is a black screen.It used to work on yahoo no problem..hope someone can help me..Thx

I try and try to get my webcam to work on yahoo messager but it a black screen... cam work when i test it but not when i start it on yahoo messager.... can some 1 help me???

I just downloaded the new Yahoo messenger for Vista beta and I can't figure out how to invite someone to view my webcam, nor can I figure out how to view someones webcam how do I do this?

I have bought 3 Webcams now and none of them work for yahoo messenger. I have found other questions like this and followed the instructions but it doesn't work. When I ask someone to view my cam, it says its unavailable on their side of it. I was thinking...

I have been using my Logitech Quickcam Messenger webcam with built in mic with a Windows 2000 computer but since Friday 22nd I have had a new computer and the cam just won't play ball on it, keep getting the message "Webcam is not connected"...

I have an EasyCam webcamera that I found lying around and I don't know how to make it work through my Yahoo Messenger webcam chat. I've tried installing it into my computer first, but every time I do it says that it can't find any services to install...

i have a dell inspiron 1520, the cam works with other chat applications, and works well to capture pics on the laptop, just with messenger, i have a problem, i get a black image on the webcam with yahoo messenger

when i click my webcam in ym, it says webcam not connected. i changed the camera source already and still it said not connected.

Hi I really need help it showes a green screen but no vidieo? it says on box works with yahoo? help! thanks
