I just joined BigBlueBall…totally frustrated with the black screen when trying to use YM with my new web cam. I read through almost every post..and somewhere back on page 7..someone said you can’t use your cam with MSN and Yahoo at the same time. DUH! The logitech software was running..I could see myself there..but not when activating through Yahoo. When I closed the logitech software…Ta Dah! I was so impressed with myself..I had to leave this post! This is for all us stupid people! Cheers.
